Answer:
[tex]3.50(b+c)-28.09[/tex]
Step-by-step explanation:
Let, the number of blueberry slices = b and number of cherry slices = c.
As, each slice sells for the price of $3.50.
Thus, the revenue of total slices sold = [tex]3.50(b+c)[/tex]
Also, the money spent on ingredients of both the pie is $15.25 and $12.84 respectively.
Thus, the total selling cost of the slices = $15.25 + $12.84 = $28.09.
So, we have,
Cindy's profit = Revenue - Cost
i.e. Cindy's profit = [tex]3.50(b+c)-28.09[/tex]
Hence, the required expression is [tex]3.50(b+c)-28.09[/tex].
