Question

The amount of money spent at the gas station varies directly with the number of gallons of gas purchased. 12 gallons of gas costs $36.00. How much would 8 gallons of gas cost?

Answer 1

Answer:

$24.00

Step-by-step explanation:

12 = 36

8 = x

=> Cross multiply

=> 12 * x = 36 * 8

=> 12x = 288

=> 12x / 12 = 288 / 12

=> x = 24

8 gallons of gas costs $24.00.

Answer 2

8 gallons of gas will cost $24.

What are the types of variation or proportion ?

There are two types of variations direct variation and inverse variation.

In direct variation between two quantities if one variable increases the other also increases and vice versa.

In inverse variation of two quantities if one variable increases the other variable decreases and vice versa.

In the given question

12 gallons of gas costs $36
