Answer
Explanation:
Step1: Calculate earnings from first job
$10\times24 = 240$
Step2: Calculate earnings from second job
Base - pay: $7\times18=126$, Commission: $0.05\times2500 = 125$, Total for second job: $126 + 125=251$
Step3: Calculate earnings from third job
Base - pay: $6.85\times16 = 109.6$, Tips: $10\times16 = 160$, Total for third job: $109.6+160 = 269.6$
Step4: Calculate total earnings if take all jobs
$240+251 + 269.6=760.6$ Since $760.6>500$, taking all three jobs will achieve the goal.
Answer:
Take all three part - time jobs. Justification: The sum of earnings from all three jobs ($760.6$) is greater than the goal of $500$ dollars a week.
