Risa and Jaslyn had the same number of problem sums to do. Risa did 14 problem sums per day. Jaslyn did 11 problem sums per day. When Risa finished doing all the problem sums, Jaslyn still had 24 more problem sums to do.
- How many days did Risa take to finish all her problem sums?
- How many problem sums did Risa have to do in total?
(a)
Number of extra problem sums that Risa did per day
= 14 - 11
= 3
Number of days that Risa took to finish all her problem sums
= 24 ÷ 3
= 8
(b)
Number of problem sums that Risa had to do in total
= 8 x 14
= 112
Answer(s): (a) 8; (b) 112
