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

<em></em>

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,

<em>The cost of 1 gallon is $2.5</em>
