Let w=375
Cost = 0.07w+13.3
Plug in the value for "w" and solve for the Cost
Cost = 0.07(375)+13.3
Cost = 39.55
.
Check by plugging 39.55 back into the original equation and solve for "w"
39.55=0.07w + 13.3
26.25=0.07w
375=w [checks out]
.
.
Let w=1
Cost = 0.07w + 13.3
Cost = 0.07(1) + 13.3
Cost = 13.37
.
check by plugging 13.37 in the formula and solve for "w"
13.37 = 0.07w + 13.3
.07=.07w
1=w [checks out]
