Question

Rita just got a babysitting job. She will work about 10 hours each week and make $9 an hour. Her parents say she needs to save half, but she can spend the other half. Rita estimates she'll have around $50 of spending money each week. Is that a good estimate?

Answer 1

Rita's estimate of $50 is a good estimate, but it's not precise. If she works 10 hours a week and makes $9 an hour, her total will be $90. Half of 90 is 45. This means her spending money each week is $45.
