Number of marbles that Cody had before = 9 u
Number of marbles that Cody gave to Neave = 2 u
Number of marbles that Cody gave to Michael = 2 u
Number of marbles that Cody gave to Warren = 2 u
Number of marbles that Cody had left = 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Number of marbles that Cody had at first
= 9 u
= 9 u x 9
= 81
