Question

Melissa earns a 2% commission on the first $750 of sales she makes each week. She earns a 3% commission on the amount of her sales that are greater than $750 each week. Melissa earned $37.50 in commissions last week.
Which equations correctly calculate how much money in dollars, x, Melissa made in sales last week?


Select all that apply.


0.02(750)+0.03(750−x)=37.5


0.03(x−750)=37.5−15


15+0.03x−22.5=37.5


0.02(750)+0.03(x−750)=37.5


15−0.03x+22.5=37.5


0.03(750−x)=37.5−15

Answer 1

Answer:

0.02(750)+0.03(x−750)=37.5

Step-by-step explanation:

Given data

Melissa earns a 2% commission on the first $750 of sales

= 0.02(750)

She earns a 3% commission on the amount of her sales that are greater than $750 each week

let the amount of her sales be x

= 0.03(750-x)

Melissa earned $37.50 in commissions last week.

= $37.5

Her total earnings is $37.5

37.5= 0.02(750)+ 0.03(x-750)

37.5= 15+0.03x- 22.5

37.5-15+22.5= 0.03x

45= 0.03x

x= 45/0.03

x= 1500
