Eric had 326 pens less than Elyse. Given that they have a total of 618 pens,
- How many pens did Elyse have?
- How many pens did Eric have?
(a)
Number of pens that Elyse had = 1 u
Number of pens that Eric had = 1 u - 326
Total number of pens
= 1 u + 1 u - 326
= 2 u - 326
2 u - 326 = 618
2 u = 618 + 326
2 u = 944
1 u = 944 ÷ 2 = 472
Number of pens that Elyse had
= 1 u
= 472
(b)
Number of pens that Eric had
= 1 u - 326
= 472 - 326
= 146
Answer(s): (a) 472; (b) 146
