Oliver had 260 pens less than Xandra. Given that they have a total of 672 pens,
- How many pens did Xandra have?
- How many pens did Oliver have?
(a)
Number of pens that Xandra had = 1 u
Number of pens that Oliver had = 1 u - 260
Total number of pens
= 1 u + 1 u - 260
= 2 u - 260
2 u - 260 = 672
2 u = 672 + 260
2 u = 932
1 u = 932 ÷ 2 = 466
Number of pens that Xandra had
= 1 u
= 466
(b)
Number of pens that Oliver had
= 1 u - 260
= 466 - 260
= 206
Answer(s): (a) 466; (b) 206
