Dara spends $16 on tubes of paint and disposable brushes for an art project. Each tube of paint costs $3, and each disposable brush costs $.50. Kara purchases twice as many brushes as tubes of paint. Find the number of brushes and the number of tubes of paint that she purchases.
Use the equations below to find your answers. Show your work.
x = tubes of paint
y= disposable brushes
x + .5y = 16
y = 2x
I could figure out but I am not going to sorry:(
Answer: There are 4 tubes of paint she purchased.
Step-by-step explanation:
Since we have given that
Amount spend on tubes of paint and brushes for an art project = $16
Cost of each tube of paint = $3
Cost of each brush = $0.50
Let the price of tube of paint be 'x'.
Let the price of brush be '2x'.
So, According to question, it becomes,

Gabe goes to the mall. If b is the number of items he bought, the expression 17.91b+27 gives the amount he spent in dollars at one store. Then he spent 22 dollars at another store. Find the expression which represents the amount Gabe spent at the mall. Then estimate how much Gabe spent if he bought 4 items.
Answer:
(17.91b+27)+22 is the expression
and the estimate will be 121 because u will do 18 times 4=72 and the add 22 and then 27.
A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?
Answer:
a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.
b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:
315/x = 70/100
This is because 315 is part of the whole and is 70% of the value of x.
Step-by-step explanation:
Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.
Answer:
a. $450
b. $135
c. 70%
Step-by-step:
[tex]\frac{70}{100} = \frac{315}{450}[/tex] since these two fractions are equal to each other that means the orginal price is $450.
(sale price/original price)x100= % of original price
(315/450)x100=0.7=70%

Rachel found that the time it takes for her to make her favorite desert decreases the more times she makes its. The time is takes in minutes(M) can be modeled by: M=72-0.75n, where n is the number of times that rachel has made the desert.
A. how long will it take rachel to make her desert the fifth time?
B. after how many times will rachel be able to make her desert in 63 minutes?
C. How long will it take rachel to make her desert the 40th time? Do you think this is reasonable?
Answer:
A: 68.25 minutes
B: 12 times
C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.
Step-by-step explanation:
a: 72 -0.75*5 = 68.25
b: M=63=72-0.75n
subtract 72 from each side: -9 = -0.75n
divide each side by -0.75: n = 12
so 12 times
c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.

Answer:
600, 1400, 3000, and 5000
Step-by-step explanation:
The profit equation can be simplified.
P = 350n -(150n +1000)
P = 200n -1000 . . . . . . . . . collect terms
P = 200(n -5) . . . . . . . . . . . factor out 200
For the given numbers n, we have ...
P = 200({8, 12, 20, 30} -5) = 200{3, 7, 15, 25} = {600, 1400, 3000, 5000}
Profits for 8, 12, 20, and 30 customers are 600, 1400, 3000, and 5000, respectively.
