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.

50 cases in 44 minutes equals how many cases in 60 minutes
Blizzard [7]
To solve this, set up a proportion, crossmultiply, and solve for x. 

Let x = the unknown amount of cases in 60 minutes.

\frac{50}{44} = \frac{x}{60}
44x = 50(60)
44x = 3000

Divide both sides by 44 to isolate variable x
x = 3000 / 44
x ≈ 68.1818 (the 18s repeat forever)

Rounding to the closest case and assuming the rate stays constant, you would get approximately 68 cases in 60 minutes. If you need not round to the nearest case, you would get approximately 68.18 cases in 60 minutes.
