Part A
Answer: 89.50 dollars
---------------------------
Work Shown:
10% = 10/100 = 0.10
10% of $895 = 0.10*895 = 89.50
=====================================================
Part B
Answer: $1350
---------------------------
Work Shown:
x = amount of sales for the week
10% of x = 0.10*x = 0.10x
0.10x = amount Geoff earns in commission
He needs $135, so 0.10x = 135
Divide both sides by 0.10 to isolate x
0.10x = 135
0.10x/0.10 = 135/0.10
x = 1350
He must have $1350 in sales for the week
