Number of marbles that Luke had before = 11 u
Number of marbles that Luke gave to Archie = 2 u
Number of marbles that Luke gave to Perry = 1 u
Number of marbles that Luke gave to Nick = 3 u
Number of marbles that Luke had left = 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of marbles that Luke had at first
= 11 u
= 11 u x 8
= 88
Answer(s): 88
