A gallon of gas costs $2.50. Use the equation p=2.5g to find a total cost with price, p, and gallons, g. Match each number of gallons on the left with its equivalent dollar amount on the right.

Answer:
Step-by-step explanation:
10 gal × $2.50/gal = $25
8 gal × $2.50/gal = $20
16 gal × $2.50/gal = $40
Replace g with the number of gallons and solve:
P = 2.5G
10 gallons = 2.5 x 10 = 25.00
8 gallons = 2.5 x 8 = 20.00
16 gallons = 2.5 x 16 = 40.00
