select the correct answer. anastasia had a part - time job last year. she made $20 per hour and worked every week of the year. each week she worked 7 hours. she paid her monthly expenses and saved the rest of her earnings. at the end of the year, she had $2,000 in savings. what were her average monthly expenses, rounded to the nearest dollar? a. $440 b. $473 c. $475 d. $568

Answer

Explanation:

Step1: Calculate total annual earnings

She earns $20 per hour and works 7 hours per week for 52 weeks. So total annual earnings $E = 20\times7\times52= 20\times364 = 7280$ dollars.

Step2: Calculate total annual expenses

Let annual expenses be $x$. We know savings $S = 2000$ and $E=x + S$. So $x=E - S=7280 - 2000=5280$ dollars.

Step3: Calculate average monthly expenses

Average monthly expenses $M=\frac{x}{12}=\frac{5280}{12}=440$ dollars.

Answer:

A. $440
