Jane has 8 pens fewer than Sabrina but 30 pens more than Reggie. The three children have 170 pens altogether.
- How many pens does Reggie have?
- How many pens does Sabrina have?
(a)
Number of pens Sabrina has = 1 u
Number of pens Jane has = 1 u - 8
Number of pens Reggie has = 1 u - 8 - 30 = 1 u - 38
Total number of pens
= 1 u + 1 u - 8 + 1 u - 38
= 3 u - 46
3 u - 46 = 170
3 u = 170 + 46
3 u = 216
1 u = 216 ÷ 3 = 72
Number of pens that Reggie has
= 1 u - 38
= 72 - 38
= 34
(b)
Number of pens that Sabrina has
= 1 u
= 72
Answer(s): (a) 34; (b) 72
