Will and Lucy share some pens.
45 of Will's pens is equal to
49 of Lucy's pens. Given that Lucy has 12 pens more than Will, how many pens do they have altogether?
45 of Will's pens = 49 of Lucy's pens
Number of Will's pens = 5 u
Number of Lucy's pens = 9 u
Number of pens that Lucy has more than Will
= 9 u - 5 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Total number of pens
= 5 u + 9 u
= 14 u
= 14 x 3
= 42
Answer(s): 42
