Mary has rehearsed her ballet solo for five and a half hours. A week from now, she wants to have rehearsed at least a total of nineteen and a half h
ours. If she rehearses for the same amount of time each day for the next 7 days, at least how many hours must she rehearse per day?
If she wants 19.5 hours total, and she has already done 5.5, then you subtract 5.5 from 19.5 to get what she has remaining which is 14. then you divide 14 hours by 7 days a week and you get 2 hours
