Question

Caroline is a full-time college student planning a spring break vacation. To earn enough money for the trip, she has taken a part-time job at the local bank that pays $15.00/hr, and she opened a savings account with an initial deposit of $400 on January 15. She arranged for direct deposit of her payroll checks. If spring break begins March 20 and the trip will cost approximately $2,500, how many hours will she have to work to earn enough to pay for her vacation? If she can only work 4 hours per day, how many days per week will she have to work? How many weeks will it take?

Answer 1

With $400 down, she needs $2100.

At $15/hr, she must work 2100/15 = 140 hours, which does NOT take

deductions into account. (In reality, she will have to work MORE)

She has from Jan 15 to March 20 to raise the funds.

Assuming Jan 15 is the beginning of the work week,

the weeks are:

Jan 15,22,29

Feb 5,12,19,26 <--- is it a leap year or not???

March 5,12

She has 9 weeks to raise the funds..

140/9 = 15 hours per week.

At 4 hours per week, She needs to work at least 4 days per week.

Check:

4 hours per day * 4 days per week * 9 weeks = 144 hours

144 hours * $15/hr = $2160, BEFORE deductions
