Problema Solution
Terry wants to buy a Wii, but he is unsure if he has enough money. The Wii costs $300 and there is a 9% sales tax on it. If he has $325 does he have enough money?
Answer provided by our tutors
cost + 9% of the cost is
300 + 0.9*300 = 1.09*300 = $327
since 325<327 follows he is $2 short.
