Question 19
Solve the problem.
Marty's Tee Shirt & Jacket Company is to produce a new line of jackets with a embroidery of a Great Pyrenees dog on the front. There are fixed costs of $520 to set up for production, and variable costs of $36 per jacket. Write an equation that can be used to determine the total cost, C(x), encountered by Marty's Company in producing x jackets, and use the equation to find the total cost of producing 89 jackets.

Question 20
Solve the problem.
In a certain city, the cost of a taxi ride is computed as follows: There is a fixed charge of $2.50 as soon as you get in the taxi, to which a charge of $1.95 per mile is added. Find an equation that can be used to determine the cost, C(x), of an xmile taxi ride.
C(x) = 4.45x
C(x) = 2.50 + 1.95x
C(x) = 1.95 + 2.50x
C(x) = 2.95x
