The total cost of a cake that serves 20 people is $35.

<u>Step-by-step explanation</u>:

Total cost = y
Number of additional servings = x
The number of additional servings = 20 - 12 = 8. (x=8)

<u>The equation can be formed as</u>:

Total cost = basic cost + (No. of additional serving $\times$ cost per additional serving)
y = 25 + x1.25
Substitute x=8 in the above equation
y = 25 + 8(1.25)
y =25+10
y = 35

Therefore, the total cost of a cake that serves 20 people is $35.
