Question: Sally and Bob have made plans to go on a trip at the end of the year. They both decide to work as babysitters and save half of what they've earned for their trip. If Sally makes $6 per day and Bob makes $4 per day, how much money will they both have saved for their trip after a year?
Answer: Saly saves 1 / 2 * $6 / day = $3 / day. Since each year have 365 days, the total amount of money Sally will save in a year is $3 / day * 365 days / year = $1095 / year. Bob saves 1 / 2 * $4 / day = $2 / day. The total amount of money Bob will have saved in a year is $2 / day * 365 days / year = $730 / year. In total, Sally and Bob would have saved $730 + $1095 = $1825. The answer is 1825.
