(b) Luke's stamps

Total |
Before |
1 u + 44 |
4 u - 44 |
90 |
Change |
- 44 |
+ 44 |
|
After |
1 u |
4 u |
5 u |
(a)
Total number of stamps
= 1 u + 4 u
= 5 u
5 u = 90
1 u = 90 ÷ 5 = 18
Number of stamps that Zeph has
= 1 u + 44
= 18 + 44
= 62
(b)
Number of stamps that Luke has
= 90 - 62
= 28
Answer(s): (a) 62; (b) 28
