A music store buys a guitar at a wholesale price of $1,200 and marks the price up 50%. What is the list price of the guitar?
A$600
B$1,250
C$1,800
D$2,400
Answer & Solution
Correct answer: C. $1,800
1. First find the amount of mark-up: change 50% to a decimal, 0.50.
2. Multiply: 0.50 x 1,200 = 600, so the mark-up is $600.
3. The list price equals the wholesale price plus the mark-up.
4. Add: 1,200 + 600 = 1,800, so the guitar lists for $1,800.
5. $600 alone is just the mark-up, and $2,400 doubles the wholesale price, which would be a 100% mark-up rather than 50%.
