Question

In a pizzeria, you pay $7 for each of the first three

pizzas, and $6 for the following pizzas. How many
pizzas did Gerry's band buy, if they paid $45?​

Answer 1

7

Explanation:

if the first 3 pizzas are 7 u multiply 7x3=21 then there is 24 dollars left so you divide 24 by 6 and u get 4 then u add 3 and 4 and u get 7

Answer 2

7 pizzas.

Explanation:

First you figure out how much the first three pizzas cost. 7x3 = 21. They paid $21 for the first 3. Subtract that number from the total cost.

45 - 21 = 24. Since the rest of the pizzas were only 6 dollars, divide the remaining amount by 6.

24/6 = 4. They bought 4 additional pieces. Add the amount of pizzas they bought together.

3 + 4 = 7
