Answer 1

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
