. Imagine you are a restaurant owner. You are trying to set the menu price for the seared scallops with rice and mango salsa. Your item food cost is $6.78 and you set your food cost percentage to 33%. What would you set the price to be on the menu? *
1 point
$16
$18
$20
$21
The price of the food on the menu will be set at $21.
Cost of food item = $6.78
Food cost percentage = 33%
Let the price on the menu be represented by x.
Therefore, based on the information given, the equation to solve the question will be:
= 33% × x = $6.78
33/100 × x = $6.78
0.33 × x = $6.78
0.33x = $6.78
x = $6.78/0.33
x = $20.54
x = $21 approximately
Therefore, the price of the food on the menu will be set at $21.

Answer:
-2/3 + 1/3 = -1/3
Step-by-step explanation:
using addition to solve a fraction with the same base
step 1: take the denominator of both fractions and clear them from the equation
ex: -2/3 + 1/3 = ? (-2 + 1 = ?)
step 2: solve the new equation -2 + 1 to get your answer of
ex: -2 + 1 = ? (-2 + 1 = -1)
step 3: since both denominators of the fractions have the same number then our answer will also have a denominator of 3 giving us the answer to the problem -2/3 + 1/3 = ? is -1/3

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.
How fast did Car B travel?
(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)
Answer:
60mph
Step-by-step explanation:
2s - 30 = 1.5s
2s - 1.5s = 30
.5s = 30
s = 60 mph is car B's speed

4. The first two numbers in a sequence are 3, 9.
a. If this is an arithmetic sequence, what are the next 2 terms?
Answer:
15 & 21Step-by-step explanation:
If this is an AP, the common difference is:
9 - 3 = 6The next two terms are:
9 + 6 = 1515 + 6 = 21In the arithmetic sequence :
The next 2 term of the arithmetic sequence is:
15 , 21
A sequence in which the difference between all pairs of consecutive numbers is equal is called an arithmetic progression.
We have the following information available from the question is:
The first two numbers in a sequence are 3, 9.
We have to find the next 2 terms of the arithmetic sequence.
Now, According to the question:
The first two numbers in a sequence are 3, 9.
a1 = 3
d = 9 - 3 = 6
The next 2 term of the arithmetic sequence is:
9 + 6 = 15

Khloe needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 6 hours and charged her $59 for parts. The total was $749. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
The cost of the labor per hour is $115.
The total amount that the technician charged her is the sum of the cost for the total hours worked and the costs of the parts.
Total charge = cost of total hours worked + cost of parts
$749 = $59 + cost of total hours worked
Cost of total hours worked = $749 - $59
Cost of total hours worked = $690.
In order to determine the cost per hour of labour, divide the total cost of total hours worked by the hours worked.
$690 / 6 = $115.
