Answer:
Cake will have to sell for $30.857
Explanation:
Contribution is sales value less variable cost
Contribution margin(CMR) is the percentage of the selling price that is earned as contribution.
CMR for Pie = 11/18× 100 = 61.%
Let the price of Cake be y
contribution per unit = y -12
0.611111111 = y -12/y
0.6111 y = y-12
12 = y -0.6111 y
12 = 0.388 y
y = 12/0.3888
y=$30.857
