Question

The original selling price of a share of stock was d dollars. The selling price for a share of the same stock at a later date was represented by the expression 1.15(0.95d). Which description could explain what happened to the price of the share of stock?
A The price decreased by 5% and then increased by 0.15%
B The price decreased by 95% and then increased by 0.15%
C The price decreased by 5% and then increased by 15%
D The price decreased by 95% and then increased by 15%

Answer 1

Original selling price = d
selling price at a later date = 1.15(0.95d)

0.95d means that the original price was discounted by 5%
1.15 means that the price increased by 15%

So the correct answer choice is: 

C The price decreased by 5% and then increased by 15%
