Katie works in a shoe store where she is paid $150 weekly and a
13% commission on her sales. In January her sales total was
$3740. How much did Katie earn for the four weeks in January?

$1086.20

First let’s find her commission.

Convert 13% to a decimal
13/100=0.13
3740*0.13=468.20

Then let’s find how much she made from her weekly salary

There are 4 weeks in January, and she makes $150 each week
150*4=600

Add the commission and salary together
600+468.20=1086.2
She earned $1068.20 for the 4 weeks in January.

Hope this helped!
