Question

Based on a survey, a grocery store claims that 97% of their customers prefer the store’s brand of milk to the other available brands. Out of 210 customers, how many would you predict will prefer the store’s brand of milk?

Answer 1

6 people

Explanation

First step would be to change the % into a number to help us out.

97% = 97/ 100 = 0.97

after that we need to multiply by the total number of costumers

210 x 0.97 = 203.7

since you cant have a 0.7 part of a person we say 204 will buy the store brand milk

after that we subtract the total costumers from the store brand costumers and we get our answer

210 -204 = 6
