C(q) = mq + b
The equation above is the linear cost model, in which m represents the costs per unit produced and b represents the fixed costs. What is the linear cost function for producing q toasters?
C(q) = 300q + 5725
C(q) = 300q + 5425
C(q) = 6q + 5425
C(q) = 6q + 5725
P(q) = R(q) – C(q)

A hotel plans to install a new paved area around its 12-foot-by-20-foot swimming pool. The paved area will consist of a sidewalk of uniform width around three sides of the pool and an extended sun deck area on the fourth side, as shown in the illustration above. The length y of the sun deck will be three times the width x of the sidewalk. If the paved area is twice the pool area, what is the length of the sun deck area to the nearest tenth of a foot?
