Answer:
P = 2.5g | $82.50
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.
