Question
Katrina and her friends ordered for 5 pizzas. If they are charged $40, cost of 9 pizzas at the same rate is __________.
- 70
- 72
- 69
- 75
Hint:
In this question, we first found the cost of one pizza and then multiplied it with 9 to get the cost of all 9 pizzas.
The correct answer is: 72
Step 1 of 1:
In the question, they have given the price of 5 pizzas as 40 dollars and asked to find the prize of 9 pizzas.
The cost of 5 pizzas = $40
Therefore the cost of one pizza = 40/5 = $8
the cost of 9 pizzas = 8*9 = $72
Final Answer:
The right choice is-- b. 72
