Answer:

a) About 48 of the shoppers, that is 230\frac{21}{100} of the shoppers, received a free set of​ earbuds.

b) About 58 shoppers, that is \frac{230}{4} received ​$5 off their first​ purchase.

Step-by-step explanation:

a. About how many shoppers received a free set of​ earbuds?

21% out of 230. So

230\frac{21}{100} = 2.3(21) = 48.3

About 48 of the shoppers, that is 230\frac{21}{100} of the shoppers, received a free set of​ earbuds.

b. About how many shoppers received ​$5 off their first​ purchase?

25% out of 230, so:

230\frac{25}{100} = 230\frac{1}{4} = \frac{230}{4} = 57.5

About 58 shoppers, that is \frac{230}{4} received ​$5 off their first​ purchase.
