14. On March 1 Tessa Obee deposited her IRS refund check for $9,364.85 in a savings account at State Bank. The account pays 4 percent interest calculated on a daily basis. Five days later on March 6 she withdrew $1,000.00. On March 18, 12 days later, she withdrew $2,000.00. On March 28, 10 days later, she withdrew another $2,000.00. Three days later on March 31 interest was computed. How much simple interest did her money earn?

Answers

Answer:

Her money earned a simple interest of $24.55.

Step-by-step explanation:

Since Tessa deposited $9364.85 and she gets 4% interest on daily basis, then before she withdraws $1000 after 5 days, she must've gotten an interest of:

9364.85 x 4% × (5/365) ≈ 5.13

After withdrawing $1000, she has $8364.85. If this remains in the account for 12days, as we have in the question, then the interest on that will be:

8364.85 x 4% × (12/365) ≈ 11.00

After withdrawing $2000, she has $6364.85. If this remains for 10days, her interest would be:

6364.85 x 4% × (10/365) ≈ 6.98

After withdrawing $2000, she has $4364.85. If this remains for 3days, her interest would be:

4364.85 x 4% × (3/365) ≈ 1.44.

In totality, her interest would be: 5.13 + 11.00 + 6.98 + 1.44 = 24.55.

Hence, her money earned a simple interest of $24.55.

Line j passes through points (10, 10) and (1, 3). Line k is parallel to line j. What is the slope of line k?

Answers

Answer:

= (10-3) ÷ (10-1) = 7 ÷9 = 7/9

Step-by-step explanation:

As they are parallel, their slopes are the same. So if we find slope of line j we find slope of line k when we have two points of one line like (x1 , y1) and (x2 , y2) the slope of that line is (y2-y1) ÷ (x2-x1)

x=-32/-16

x=2

Answer: x=2

Step-by-step explanation:

Simplify the equation

-12+29= 4x-3

Subtract 29 from both sides

12x=4x-32

Subtract 4x from both sides (Simplify)

-16x=-32

Divide both sides by -16

Two car rental companies charge an initial rental fee plus a fee per day. The table shows the total costs of renting a car for x days from
Discount Car Rentals. The total costy (in dollars) of renting a car for x days from Pay Less Rentals is represented by the equation
y=25x + 170. Which rental company charges less per day? How many days must you rent a car for the total costs to be the same?

Answers

Answer:

Step-by-step explanation:

Two car rental companies charge an initial rental fee and a fee per day.

Total cost for the company A is given by the equation,

y = 25x + 170

Car A charges $25 per day. [Slope of the line]

Another car rental company B charges as per table attached.

Per day car rental for the company B = [tex]\frac{270-180}{4-2}[/tex]

                                                              = [tex]\frac{90}{2}[/tex]

                                                              = $45 per day

Therefore, per day rental charged by company A is less.

Let the equation for the car rental by company A is,

y = mx + b

where m = per day rental charged by company A = $21.5

y = 45x + b

One point (2, 180) from the table lies on the equation.

Therefore, 180 = 45(2) + b

b = 180 - 90

b = 90

So the equation will be,

y = 45x + 90

If both the company charge the same after x day of rental,

45x + 90 = 25x + 170

45x - 25x = 170 - 90

20x = 80

x = 4

After 4 days car rentals for both the companies will be same.

n − 9/4= 2n − 7/9 please add work

Answers

Answer:

- 1 17/36

Step-by-step explanation:

Step 1:

n - 9/4 = 2n - 7/9       Equation

Step 2:

- 9/4 = n - 7/9     Subtract n on both sides

Step 3:

- 81/36 = n - 28/36     Find common denominator

Step 4:

- 53/36 = n       Add 28/36 on both sides

Answer:

n = - 1 17/36     Convert

Hope This Helps :)

Answer:

n= -53/36

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

n+ −9/4 = 2n+ −7/9

Step 2: Subtract 2n from both sides.

n+ -9/4 −2n=2n+ −7/9−2n−n+ −9/4 = −7/9

Step 3: Add 9/4 to both sides.

−n+ −9/4+9/4=−7/9+9/4   −n=53/36

Step 4: Divide both sides by -1.

−n/-1=53/36/−1n=−53/36

11. During an evening out, Dean paid a cab driver $20. He
then spent $25 on dinner and half of his remaining money on a painting. He bought an umbrella for $23.75 and had $42.15 left. How much money did Dean have at the beginning of the weekend?

Answers

Let total amount be x.
Cab - $20
Dinner - $25
Remaining Amount- (x-45)
Hlf of this amount was spent on painitng. So, net cash in hand is (x-45)/2.

out of this cash in hand, he has gt umbrella for 23.75, and balance cash is 42.15.

so, (x-45)/2=23.75+42.15

(x-45)/2=65.9
x-45=131.8
x=176.8

Amount Dean had at the beginning of the weekend = $176.8

Answer:

$176.80

Step-by-step explanation:

$42.12 (what he had left) + 23.75 = 65.90

65.90 (Amount he had after he bought the painting) + 65.90 (The other half of his remaining money he spent on the painting) = 131.80

131.80 + 25 + 20 = 176.80

= $176.80
