Yesterday, Justin had 51 cupcakes and 11 croissants. This morning, he sold 29 cupcakes and bought some more croissants. Now he has four times as many croissants as cupcakes. How many croissants did he buy today?

1 u |
4 u |
Number of cupcakes in the end

= 22
1 u = 22
Number of croissants in the end
= 4 u
= 4 x 22
= 88
Number of croissants that Justin bought today
= 4 u - 11
= 88 - 11
