Answer

This is a Before After question. 

   Before   Transfer  After   
Linus 8u -36 8u – 36
Omar 7u   7u
Total 15u   15u – 36

(8u -36)/1 = 7u/2

16u – 72 = 7u

16u – 7u = 72

9u = 72

1u = 72 ÷ 9 = 8

15u = 15 × 8 = 120 cookies

Let the number of cookies baked by Linus be 8x

Let the number of cookies baked by Omar be 7x

8x-36 = 7x/2

8x-36 = 3.5x

4.5x = 36

x=36/4,5 = 8

Total cookies baked = 15x = 15(8) = 120
