Caden had
18 as many stamps as Cole. Cole had twice as many stamps as Peter. If Caden had 87 stamps fewer than Peter,
- how many stamps did Caden have?
- how many stamps did they have altogether?
(a)
Number of stamps that Caden had = 1 u
Number of stamps that Cole had = 8 u
Number of stamps that Peter had = 8 u ÷ 2 = 4 u
Number of stamps that Caden had fewer than Peter
= 4 u - 1 u
= 3 u
3 u = 87
1 u = 87 ÷ 3 = 29
Number of stamps that Caden had
= 1 u
= 29
(b)
Total number of stamps that they had
= 1 u + 8 u + 4 u
= 13 u
= 13 x 29
= 377
Answer(s): (a) 29; (b) 377
