Tyra buys 14 gallons of gas for $35. How could she figure out how much 1 gallon of gas cost

defon

Answer:

The cost of 1 gallon is $2.5

Step-by-step explanation:

Given

Cost of 14 gallons = $35

Required

Determine the cost of 1 gallon

From the given parameters, we have:

$14\ gallons = \$35$

Divide both sides by 14

$\frac{14\ gallons}{14} = \frac{\$35}{14}$

$1\ gallon = \frac{\$35}{14}$

$1\ gallon = \$2.5$

Hence,

The cost of 1 gallon is $2.5
