Question

Timothy earns a 15% commission on each household appliance he sell. If he sells 6 toasters at $20 each and a blender for $105.50, how much does he earn in commission?

Answer 1

6x20=120
120+105.50=225.50
we round 225.50 to the nereast hunderd=200
100 goes in 200, 2 times
15x2=30
30/200=6.6
25.5 goes in 100 , 1/4
15/25.5=1.70
6.60+1.70=8.30
