Question

A desktop computer was originally selling for $600. Due to changing models, the first markdown was 15 percent and the second markdown 20 percent. The computer still did not sell so a final markdown of 10 percent was taken. The sale price is currently:

a. $400.00

b. $367.20

c. $330.00

d. none of the above

Answer 1

The final sale price of the computer, after applying three consecutive markdowns to the original price of $600, is calculated to be $367.20, which corresponds to option (b).

Step-by-step explanation:

The student's question asks about calculating the final sale price of a desktop computer after successive markdowns of 15%, 20%, and 10%. To find the sale price, we need to apply each markdown sequentially to the original price of $600.

1. First markdown of 15%: This results in a discount of 15/100 × $600 = $90, so the new price becomes $600 - $90 = $510.

2. Second markdown of 20%: Now we apply a 20% discount on the new price of $510. The discount is 20/100 × $510 = $102, leading to a further reduced price of $510 - $102 = $408.

3. Final markdown of 10%: The last markdown of 10% on the price of $408 gives a discount of 10/100 × $408 = $40.80, and thus the final sale price is $408 - $40.80 = $367.20.
