an appliance salesman receives a commission of 15% of all sales. last week he sold a refrigerator priced at $755,a dishwasher priced at $450, and a range priced at $535. what is the total commission he earned for the week?
1)$26.10
2)$104.40
3)$116.00
4)$261.00
5)$1740.00

commission means how much he made.
Anyways, I worked it out as follows
Add all the prices up
755+450+535=1740
Set up a proportion
x/1740=15/100
x = (1740*15)/100
4)$261.00
