B. 3.5( b + c ) - 28.09
C. $108.41
Step-by-step explanation:
The best expression to use to find the total profit of Cindy's pie is 3.5(b+c) - 28.09. The total profit is the total revenue - total cost.
To put it into perspective, let's try an example.
b = 5
c = 12
Total profit = 3.5(b + c) - 28.09
= 3.5 (5 + 12) - 28.09
= 3.5 (17) - 28.09
= 59.5 - 28.09
Total profit = $31.41
Now for part B, we simply use the expression and substitute the values.
b = 24
c = 15
Total profit = 3.5(b + c) - 28.09
= 3.5(24 + 15) - 28.09
= 3.5(39) - 28.09
= 136.5 - 28.09
Total profit = $108.41
