Question

3. You sell storm windows and doors. You receive a straight

commission of 8% of the selling price of each storm window

and 12% of the selling price of each door. What total

commission will you receive for selling storm windows

worth $5,400 and doors worth $28,790?

Answer 1

You receive: $3,886.80

Total commission: nearly 11%

Explanation:

Windows:

Commission = 8% or 0.08 as decimal

Sold = $5,400

You receive:

`\$5,400\cdot 0.08=\$432`

Doors:

Commission = 12% or 0.12 as decimal

Sold = $28,790

You receive:

`\$28,790\cdot 0.12=\$3,454.80`

Total:

You receive:

`\$432+\$3,454.80=\$3,886.80`

Windows and doors:

`\$5,400+\$28,790=\$34,190`

Commission:

`(3,886.80)/(34,190)\cdot 100\%\approx 11\%`
