Vincent has twice as many erasers as Owen. Owen has 8 more erasers than Flynn. They have a total of 56 erasers.
- How many erasers does Vincent have?
- How many erasers does Flynn have?
(a)
Number of erasers that Owen has = 1 u
Number of erasers that Flynn has = 1 u - 8
Number of erasers that Vincent has = 2 u
Total number of erasers
= 1 u + 1 u - 8 + 2 u
= 4 u - 8
4 u - 8 = 56
4 u = 56 + 8
4 u = 64
1 u = 64 ÷ 4 = 16
Number of erasers that Vincent has
= 2 u
= 2 x 16
= 32
(b)
Number of erasers that Flynn has
= 1 u - 8
= 16 - 8
= 8
Answer(s): (a) 32; (b) 8
