Question

Researchers estimate that 15 out of every 25 customers at a store make purchases with a credit card. If the store has 600 customers tomorrow, how many credit card changes can be expected?

Answer 1

360

Explanation:

Number of customers who make purchases with a credit card

=15 out of every 25=
`(15)/(25)=(3)/(5)`

The fraction 3/5 represents the part of the customer that makes purchases with credit cards.

Therefore if there are 600 customers tomorrow, 3/5 of them will use a credit card.

`(3)/(5) X 600=360`

360 credit card can be expected.
