Question

Bobby paid a total of $\$43.50$ for renting 1 skateboard and 1 pair of rollerblades. Bobby started his rental of both items at the same time and ended his rental of both items at 6.30 p.m. What time did Bobby start his rental?
Answer: 3.30 p.m.

Worked solution

  1. Renting both items together costs $\$10 + \$4.50 = \$14.50$ per hour. Duration $= \$43.50 \div \$14.50 = 3$ hours. Start time $= 6.30\text{ p.m.} - 3\text{ h} = 3.30\text{ p.m.}$
