Tommy has five times as many stamps as Mark. Mark has 11 more stamps than Fabian. They have a total of 94 stamps.
- How many stamps does Tommy have?
- How many stamps does Fabian have?
(a)
Number of stamps that Mark has = 1 u
Number of stamps that Fabian has = 1 u - 11
Number of stamps that Tommy has = 5 u
Total number of stamps
= 1 u + 1 u - 11 + 5 u
= 7 u - 11
7 u - 11 = 94
7 u = 94 + 11
7 u = 105
1 u = 105 ÷ 7 = 15
Number of stamps that Tommy has
= 5 u
= 5 x 15
= 75
(b)
Number of stamps that Fabian has
= 1 u - 11
= 15 - 11
= 4
Answer(s): (a) 75; (b) 4
