Problema Solution
Tom bought a computer for 15% off from the list price of p dollars. If the sales tax was 8%, how much did he pay for the computer including sales tax?
Answer provided by our tutors
List Price = p
Sale Price = p - 0.15 * p = (1 - 0.15)*p = 0.85p
Tax on Sale Price = 0.08 *0.85 * p =0.068*p
Total Price = Sale Price + Tax on Sale Price
Total Price = 0.85 * p + 0.068 * p
Total Price = (0.85 + 0.068) * p
Total Price = 0.918 * p
Tom paid 0.918p for the computer.
