Tim had 355 buttons less than Julie. Given that they have a total of 627 buttons,
- How many buttons did Julie have?
- How many buttons did Tim have?
(a)
Number of buttons that Julie had = 1 u
Number of buttons that Tim had = 1 u - 355
Total number of buttons
= 1 u + 1 u - 355
= 2 u - 355
2 u - 355 = 627
2 u = 627 + 355
2 u = 982
1 u = 982 ÷ 2 = 491
Number of buttons that Julie had
= 1 u
= 491
(b)
Number of buttons that Tim had
= 1 u - 355
= 491 - 355
= 136
Answer(s): (a) 491; (b) 136
