A department store offered a 10% discount on all humidifiers. They also stated that the first 50 customers would receive an additional 5% discount off the sale price. If you purchase a humidifier that sells for $169 and you are among the first 50 customers, what will your total discount be (a) in dollar amount and (b) in percent?

Answer:

The discount was A) $ 24.51 and B) 14.5% of the value.

Explanation:

Since a department store offered a 10% discount on all humidifiers, and they also stated that the first 50 customers would receive an additional 5% discount off the sale price, if I purchase a humidifier that sells for $ 169 and I are among the first 50 customers, to determine what will my total discount be (a) in dollar amount and (b) in percent, the following calculation must be performed:

100 - 10 = 90

100 - 5 = 95

(169 x 0.9) x 0.95 = X

152.1 x 0.95 = X

144.49 = X

169 = 100

144.49 = X

144.49 x 100/169 = X

85.5 = X

Therefore, the discount was A) $ 24.51 and B) 14.5% of the value.
