7. John's seafood restaurant is trying to estimate its profits. John has found that on average, each meal served costs the restaurant $14.56 and takes in $17.12. John has also found that on average, each beverage served costs the restaurant $1.20 and takes in $5.40. If c customers order a meal, and half of those customers order a beverage, which of the following functions models the restaurant's total profit?

f (c) = 17.12c - 14.56c + 5.40 (.5c) - 1.20 (.5c)

f (c) = 17.12c - 14.56c + 5.4c - 1.20c

f (c) = 14.56c - 17.12c + 1.20c - 5.40c14.56c - 17.12c + 12 (.5c) - 5.40 (.5c)

    f (c) = 17.12c - 14.56c + 5.40 (.5c) - 1.20 (.5c)

    Step-by-step explanation:

    Let's build the f (c) function by steps.

    There are c customers.

    John has found that on average, each meal served costs the restaurant $14.56 and takes in $17.12.

    So, the costs for the restaurant are negative, and what takes positive.

    f (c) = 17.12c - 14.56c

    Now the final part

    John has also found that on average, each beverage served costs the restaurant $1.20 and takes in $5.40.

    Half of these customers order a beverage, and this is why we multiply by 0.5.

    So

    f (c) = 17.12c - 14.56c + 5.40 (.5c) - 1.20 (.5c)

    f (c) = 17.12c - 14.56c + 5.40 (.5c) - 1.20 (.5c)

    Step-by-step explanation:

    Profit is the difference between revenue (17.12c + 5.40 (.5c)) and cost (14.56c+1.20 (0.5c)). That difference is expressed by the function shown above.
