Question

A video game sells at Arnolds for $14.99. Arnold's marks the game up at 40% of the selling price. What is the cost of the game to Arnold? A. $6.00 B. $6.50 C. $8.99 D. $9.10

Answer 1

X = cost in dollars
selling price = 14.99 dollars
40% of selling price = 0.4*14.99 = 5.996 which rounds to 6.00 dollars

Arnold wants a profit of $6 per video game

Profit = Revenue - Cost
6 = 14.99 - x
6+x = 14.99-x+x ... add x to both sides
x+6 = 14.99
x+6-6 = 14.99-6 ... subtract 6 from both sides
x = 8.99

Answer: Choice C) $8.99

Answer 2

To answer this question, you do

14.99*40/100

This equals 5,996.

Therefore, the answer is A.
