A. $28.09 B. $55.91 C. $108.41 D. $136.50

Answer 1

B. 3.5( b + c ) - 28.09

C. $108.41

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
