We have been given that during one particular sales day, 75% of the store's customers paid with credit cards. There were 60 customers that day.
To find the number of people, who used credit card, we will find 75% of 60.

The number of people who use a credit card = 0.75 x 60
The number of people who use a credit card = 45
