Question

Berto has $12 to put gas in his car. If gas costs $3.75 per gallon,which ordered pair raw laying number of gallons of gas, x,to the total cost of gas ,y , includes the greatest amount of gas berto Can buy?

Answer 1

(3.2, 12)

Explanation:

Total cost for gas = $12

Cost per gallon = $3.75

Letting total cost of gas be y and number of gallons be x, maximum number of gallons of gas he can buy would be ;

Total cost of gas/ cost per gallon = 12 / 3.75 = 3.2 gallons

Therefore , the coordinate pair (x, y) = (3.2, 12)

Answer 2

Amount of gas = 3.2 gallons

Required coordinate pair is (3.2, 12)

Explanation:

Let x be the number of gallon of gas.

Given:

Berto has ⇒ y = $12

Gas cost per gallon ⇒ $3.75

Solution:

Using below formula.

Number of gallon of gas =
`(Total\ cost)/(Gas\ cost\ per\ gallon)`

Now, we substitute total cost and gas cost per gallon.

`x=(12)/(3.75)`

`x=3.2\ gallon\ of\ gas`

Therefore, Berto can buy 3.2 gallon of gas and required coordinate pair is (3.2, 12).
