Vaidev had 245 erasers more than Raeann. Given that they have a total of 511 erasers,
- how many erasers did Raeann have?
- how many erasers did Vaidev have?
(a)
Number of erasers that Vaidev that = 1 u + 245
Number of erasers that Raeann had = 1 u
Total number of erasers
= 1 u + 245 + 1 u
= 2 u + 245
2 u + 245 = 511
2 u = 511 - 245
2 u = 266
1 u = 266 ÷ 2 = 133
Number of erasers that Raeann had
= 1 u
= 133
(b)
Number of erasers that Vaidev had
= 1 u + 245
= 133 + 245
= 378
Answer(s): (a) 133; (b) 378
