Tom had 244 erasers more than Jean. Given that they have a total of 450 erasers,
- how many erasers did Jean have?
- how many erasers did Tom have?
(a)
Number of erasers that Tom that = 1 u + 244
Number of erasers that Jean had = 1 u
Total number of erasers
= 1 u + 244 + 1 u
= 2 u + 244
2 u + 244 = 450
2 u = 450 - 244
2 u = 206
1 u = 206 ÷ 2 = 103
Number of erasers that Jean had
= 1 u
= 103
(b)
Number of erasers that Tom had
= 1 u + 244
= 103 + 244
= 347
Answer(s): (a) 103; (b) 347
