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

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
