Mrs. Thomas car averages 23 miles per gallon. How many gallons of gasoline will she need in order to make the round trip ? If the price of gasoline is $2.13 per gallon, what is the cost of the gasoline for the entire trip? In addition to paying for the gasoline, Mrs. Thomas must also pay $13.92 fo her lunch and $32.98 for her dinner. What is the total amount of her meal expenses?

a. What is the total amount of her gasoline and meal expenses?
b. What operation did you use to figure it out ?

a. $70.43

b. 23.43 + 13.92 + 32.98 = t (UNSURE)

Step-by-step explanation:

Since Mrs. Thomas is driving 231 miles using 23 miles per gallon, let's start by dividing 231 by 23

We need to round 10.043... to 11 because you can't get part of a gallon.

Now, we need to multiply 2.13 by 11 to get the total amount of money for gasoline.

$

We also have the aditional meal expenses, which are $13.92 and $32.98.

We can use an equation to solve. Our total amount will be represented by t.

Hope this helps! Part b seems a bit confusing. I'll fix my answer if you could clarify, like if I do "communative property" or write equation. :))

the answer is 5/3x+7/5y+7

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
