b. 30
c. 45
d. 50

the anwser is C.

Step-by-step explanation:

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 = 75/100 x 60

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

The number of people who use a credit card = 45

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

both equations and proportions are better.
