To find out how long it will take for Marina to make 108 cupcakes, we can set up a proportion:

36 cupcakes / 45 minutes = 108 cupcakes / x minutes

Cross multiplying:

36 * x = 108 * 45

Solving for x:

x = (108 * 45) / 36

x = 135 minutes

So, it will take Marina 135 minutes to make 108 cupcakes.
