(a)
Before
Number of stamps that Carl had = 1 u + 214
Number of stamps that Rael had = 1 u
After
Number of stamps that Carl had = 1 u + 214 + 53 = 4 u
Number of stamps that Rael had = 1 u
1 u + 214 + 53 = 4u
1 u + 267 = 4 u
4 u - 1 u = 267
3 u = 267
1 u = 267 ÷ 3 = 89
(a)
Number of stamps that Rael had
= 1 u
= 89
(b)
Number of stamps that Carl and Rael had in the end
= 4 u + 1 u
= 5 u
= 5 x 89
= 445
Answer(s): (a) 89; (b) 445
