The number of cookies that Jenson had remains unchanged.
If Jenson had another 11 cookies in the end, the number of cookies that Natalie and Jenson had would be the same.
5 u - 5 = 1 u + 11
5 u - 1 u = 11 + 5
4 u = 16
1 u = 16 ÷ 4 = 4
Total number of cookies
= 5 u + 1 u
= 6 u
= 6 x 4
= 24
Answer(s): 24
