38 as many marbles as Lucy. After Asher bought another 64 marbles, he had 11 less marbles than Lucy. How many marbles did Asher have at first?

8 u |
Lucy had 11 more marbles than Asher in the end. So, if Asher had another 11 marbles, he would have the same number of marbles as Lucy.
8 u = 3 u + 64 + 11
8 u - 3 u = 64 + 11
5 u = 75
1 u = 75 ÷ 5 = 15
Number of marbles that Asher had at first
= 3 u
= 3 x 15
= 45
Answer: 45
