Question

David bought a shirt for $14.50 and a pair of pants for $21.50. David had a coupon for 33% off the pair of pants. Which expression can David use to calculate the total price of his purchase?

A.(14.50 + 21.50)(0.33) . C.14.50 + (21.50)(0.33)
B.(14.50 + 21.50)(0.67) . D.14.50 + (21.50)(0.67)

Answer 1

D. 14.50+ (21.50)(0.67)

Explanation:

A and B are automatically eliminated because 14.50 has to be added on. Since you are taking 33% off, you have to multiply 21.50 by 67 because that is how much you ARE paying.

Answer 2

D. 14.50 + (21.50)(0.67)

Explanation:

Multiply the cost of the pants by the percent discount and add it to the cost of the shirt.
