Lui and Kathy share some pens.
34 of Lui's pens is equal to
37 of Kathy's pens. Given that Lui has 24 pens less than Kathy, how many pens do they have altogether?
34 of Lui's pens = 37 of Kathy's pens
Number of Lui's pens = 4 u
Number of Kathy's pens = 7 u
Number of pens that Lui has less than Kathy
= 7 u - 4 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Total number of pens
= 4 u + 7 u
= 11 u
= 11 x 8
= 88
Answer(s): 88
