Question

Amber is saving her money for new figure skates. They cost $149.99. She gets $20 a week allowance and babysits for 2 hours a week at $5.50 an hour. She gets paid once week. She pays $2.50 a week for school lunch. She saves the rest of money. Write an inequality to find the number of weeks it will take her to save enough money for the skates. How long will it take her to save enough money to buy the skates?

Answer 1

She gets $20 per week allowance.......she babysits 2 hrs a week at 5.50 per hr.....so she gets (2 * 5.50) = $ 11 per week from babysitting...so she is making a total of (20 + 11) = $ 31 per week. But she pays 2.50 a week for school lunch.......so she is basically making (31 - 2.50) = 28.50 per week.

28.50w < = 149.99
w < = 149.99 / 28.50
w < = 5.26 weeks....but if u need it rounded, it would take her approximately 6 weeks....because 5 weeks wouldn't be enough time
