Zane had
112 as many buttons as Cole. Cole had twice as many buttons as Bobby. If Zane had 120 buttons fewer than Bobby,
- how many buttons did Zane have?
- how many buttons did they have altogether?
(a)
Number of buttons that Zane had = 1 u
Number of buttons that Cole had = 12 u
Number of buttons that Bobby had = 12 u ÷ 2 = 6 u
Number of buttons that Zane had fewer than Bobby
= 6 u - 1 u
= 5 u
5 u = 120
1 u = 120 ÷ 5 = 24
Number of buttons that Zane had
= 1 u
= 24
(b)
Total number of buttons that they had
= 1 u + 12 u + 6 u
= 19 u
= 19 x 24
= 456
Answer(s): (a) 24; (b) 456
