Heather works in an appliance store. She earns $1,500 per month plus a commission of 4% on her monthly sales. Her weekly sales amounts this month were $2,400, $3,200, $5,200, and $1,200. What is her total income this month.

$1980

Step-by-step explanation:

First, let’s find out her monthly sales by adding up the 4 weekly sales.

2400+ 3200 + 5200 + 1200 = 12000

Next, find the amount of commission on 12000

4%/100=0.04

12000*0.04=480

Next add her commission to her monthly wage of 1500

1500+480=1980

you can use a^2+ b^2=c^2
