Answer:
(a) He solved m/5 problems everyday.
(b) He solved 75 problems during his vacation.
(c) If he solved 15 problems per day, then 75 problems were assigned for homework. Otherwise, he had m problems assigned for homework.
Step-by-step explanation:
(a) m math problems were assigned, and he completed them in 5 days. So divide the number of problems with the number of days.
(b) If he was solving 15 problems per day, then 15×5 = 75 problems.
(c) 75 problems were assigned for homework if he was doing 15 problems a day. Otherwise, he was assigned m problems for homework.
