Question 551197
When determining interest on a sale the formula is P = S(1+i) where P is the final price, S is the marked sales price and i is the interest or tax.<P>
The wording of this problem isn't clear.  If he paid $95.89 including the 8% (.08) tax and the problem asks for the marked price (before tax) then it's:<P>
95.89 = S(1.08)
S = 95.89/1.08 = $88.79<P>
If he paid 95.89 (the marked price) plus 8% (.08) tax then it's:<P>
P = 95.89(1.08)=$103.56
