The price, P, that Eric pays for gas varies directly with the number of gallons, g, he buys. It costs him $50 to buy 20 gallons of gas. Write the equation that relates P and g. How much would 33 gallons cost Eric?

P = 2.5g             |             $82.50

Step-by-step explanation:

20 multiplied by 2.5 gets you 50 which means that every gallon costs $2.50. That means the price is equal to $2.50 times the number of gallons being purchased. To calculate how much 33 gallons would cost Eric, we need to use this equation.

P = 33(2.5)

P ends up being $82.50. That is the cost of 33 gallons.

5050
