B) $78.75
C) $101.25
D) $112.50

Answer 1

Frank will need 4 pizzas to feed 20 students, at a cost of $11.25 per pizza, amounting to a total of $45.00.

Step-by-step explanation:

To calculate the amount of money Frank needs to feed a class of 20 students, we first have to determine how many pizzas he will need. Since each pizza feeds 5 students, for 20 students, Frank will need:

Number of Pizzas = Total Students ÷ Students Per Pizza = 20 ÷ 5 = 4 pizzas

Now we can calculate the total cost:

Total Cost = Number of Pizzas x Cost Per Pizza = 4 x $11.25 = $45.00

Therefore, the correct answer to how much money Frank will need to feed a class of 20 students is:

Answer: B) $45.00
