Q. Rita just got a babysitting job. She will work about 1010 hours each week and make $9\$9 an hour. Her parents say she needs to save half, but she can spend the other half.\newlineRita estimates she'll have around $50\$50 of spending money each week. Is that a good estimate?\newlineChoices:\newline(A)Yes.\newline(B)No, it is much too high.\newline(C)No, it is much too low.
  1. Calculate Total Earnings: Calculate Rita's total weekly earnings.\newlineRita earns $9\$9 per hour and works 1010 hours each week.\newlineTotal earnings = \$9\/hour \times 10\ hours = \$90.
  2. Calculate Spending Amount: Calculate how much Rita can spend.\newlineRita's parents say she needs to save half of her earnings, so she can spend the other half.\newlineAmount she can spend = $90/2=$45\$90 / 2 = \$45.
  3. Compare Estimate with Calculation: Compare Rita's estimate with the calculated spending amount. Rita estimates she will have around $50\$50 to spend, but the calculation shows she will have $45\$45.
