Desiree works 28 hours per week. She has a monthly income of $120 from investments. Desiree also plays in a band one night a wee
k making $200. She has a total annual income of $49,696. Desiree wants to ask her boss for a raise so that next year she can have a total income of $51,880. Assuming the other incomes remain the same, how much of an hourly raise will Desiree need?
You could spend time working out how much she earns from the band per year, and how much from her investments, and how much per hour from her job, but none of that is necessary for the answer.
The amount of raise she requires per year is
51 880 - 49 696 = 2 184
2184/52 = 42 per week
42/28 = 1.5 per hour
