Tommy had 218 buttons more than Victoria. Given that they have a total of 414 buttons,
- how many buttons did Victoria have?
- how many buttons did Tommy have?
(a)
Number of buttons that Tommy that = 1 u + 218
Number of buttons that Victoria had = 1 u
Total number of buttons
= 1 u + 218 + 1 u
= 2 u + 218
2 u + 218 = 414
2 u = 414 - 218
2 u = 196
1 u = 196 ÷ 2 = 98
Number of buttons that Victoria had
= 1 u
= 98
(b)
Number of buttons that Tommy had
= 1 u + 218
= 98 + 218
= 316
Answer(s): (a) 98; (b) 316
