Zeph had 251 buttons less than Pamela. Given that they have a total of 617 buttons,
- How many buttons did Pamela have?
- How many buttons did Zeph have?
(a)
Number of buttons that Pamela had = 1 u
Number of buttons that Zeph had = 1 u - 251
Total number of buttons
= 1 u + 1 u - 251
= 2 u - 251
2 u - 251 = 617
2 u = 617 + 251
2 u = 868
1 u = 868 ÷ 2 = 434
Number of buttons that Pamela had
= 1 u
= 434
(b)
Number of buttons that Zeph had
= 1 u - 251
= 434 - 251
= 183
Answer(s): (a) 434; (b) 183
