Question

The Food Mart grocery store has a candy machine. Each time a child inserts a quarter, 7 candies come out of the machine. The machine holds 15 pounds of candy. Each pound of candy contains about 180 individual candies. 1 Represent the number of candies in the machine for any given number of customers. About how many customers will there be before the machine is empty? 2 Represent the amount of money in the machine for any given number of customers.

Answer 1

Answer:

The number of candies in the machine = 2700 candies

Number of customers required to empty the machine = 386

The amount of money in the machine = $96.43

Explanations:

The price of candy in the machine = 15 pounds

Each pound of candy contains about 180 individual candies.

A child can buy 7 candies with a quarter

1 pound = 180 candies

15 pounds = 180 * 15 = 2700 candies

The number of candies in the machine = 2700 candies

2) 7 candies cost 1 quarter

2700 candies will cost 2700 / 7 quarters

2700 candies will cost 385.7 quarters

Since each child inserts a quarter, there will be 386 customers to empty the machine

1 quarter = $0.25

385.7 quarters = $96.43

The amount of money in the machine = $96.43
