Read the scenario below and calculate the final selling price.

Cevap:A mechanic buys a used car for

\$3,500

and spends

\$500

on replacement parts. He marks up his total investment by

25\%

to set the asking price. A customer then negotiates a

10\%

discount off this asking price. The final selling price of the car is $\$【4500】.

4500

The total investment is the sum of the car and parts (

\$4,000

). The

25\%

markup is calculated on this total base, resulting in a

\$5,000

asking price (

\$4,000 \times 1.25

). Finally, the

10\%

discount is calculated sequentially on the new

\$5,000

asking price, giving a final selling price of

\$4,500

(

\$5,000 \times 0.90

Calculate the mechanic's total investment.

\$3,500 + \$500 = \$4,000

The markup is applied to the total cost, which includes both the initial purchase price and the cost of the replacement parts.

Calculate the asking price by applying the 25% markup to the total investment.

\$4,000 \times 1.25 = \$5,000

25\%

markup means the asking price is

125\%

of the total investment.

Calculate the final selling price by applying the 10% discount to the asking price.

\$5,000 \times 0.90 = \$4,500

The discount is taken off the new marked-up asking price, leaving

90\%

of that price to be paid.

Calculating successive percentage changes by updating the base amount for each step.
