Answer:
c. $9.50 each.
Step-by-step explanation:
For computing the selling price, first we have to compute the total price of three cakes which is shown below:
The sale value of three cakes would be
= $3 per cake × 3 cakes
= $9
And, the producer surplus is $19.50
So, the total price of cake equals to
= $9 + $19.50
= $28.50
And, the number of cake is 3
So, the selling price would be
= $28.50 ÷ 3 cakes
= $9.50 each
