Question

Gas station A has posted a chart that shows the price of gasoline in terms of the number of gallons. Gallons Price 3 9.15 5 15.25 7 21.35 Gas station B has an equation that represents the price, p, for gallons, g, of gasoline as p = $3.08g. Which gas station sells gasoline at a lower rate? What price does it charge? A. Gas station A sells gasoline at a lower rate. Its price is $3.08 per gallon. B. Gas station B sells gasoline at a lower rate. Its price is $3.05 per gallon. C. Gas station A sells gasoline at a lower rate. Its price is $3.05 per gallon. D. Gas station B sells gasoline at a lower rate. Its price is $3.08 per gallon.

Answer 1

Explanation:

To answer this, all you need to do is first figure out how much per gallon each of the gas stations offer. Because Gas station B is practically given to you by the equation, I'll show you how to interpret it:p = $3.08gp is the priceg is the gallonSo the price you will pay will be $3.08 times the number of gallons. This means that 1 gallon, if you substitute it will be $3.08.This would eliminate options A and B.Now to figure out how much Gas station A charges, just choose one of the prices. All we need to do is to divide the price given by the number of gallons:So Gas station A is lower than Gas station B.

Answer 2

C. Gas Station A sells gasoline at a lower rate. Its price is $3.05 per gallon

Explanation:

To answer this, all you need to do is first figure out how much per gallon each of the gas stations offer.

Because Gas station B is practically given to you by the equation, I'll show you how to interpret it:

p = $3.08g

p is the price

g is the gallon

So the price you will pay will be $3.08 times the number of gallons. This means that 1 gallon, if you substitute it will be $3.08.

This would eliminate options A and B.

Now to figure out how much Gas station A charges, just choose one of the prices. All we need to do is to divide the price given by the number of gallons:

`3 gallons = \$ 9.15\\\\\frac{3gallons} {3}=(\$9.15)/(3)=\$3.05`

So Gas station A is lower than Gas station B.
