Question One
The first question is just to derive a formula that represents the cost of anything bought in Idaho.
c = p + 6/100 * p
c = p + 0.6 * p
c = 1.06 p
Question Two
The second question requires an entirely different formula. You don't use the first formula. You just use it's idea. Further, you take the sales tax only when you know how much money has exchanged hands.
c = (p - 30/100 p) + 6/100*(p - 30/100 * p)
c = (p - 0.3p) + 0.06* (p - 0.3p)
c = 0.7 p + 0.06*(0.7p) Combine the right side
c = 0.7p + 0.042p Combine
c = 0.742p
33.39 = 0.742p Divide by 0.742
33.39/0,742 = p
p = 45 dollars
The original cost was 45 dollars
