(D) $25.00
(E) $31.36
Q/A-D
We can plug in the answers, which represent the wholesale price.
When the correct wholesale price is increased by 12%, a selling price of $28 must be yielded.
Since 12% = 12/100 = 3/25, the correct answer choice must be a multiple of 25; otherwise, increasing the answer choice by 3/25 will not yield an integer value of 28.
Only
D -- $25 -- is a multiple of 25.
The correct answer is
D.
Answer choice
D:
25 + (3/25)(25) = 25+3 = 28.
