The cost of printing cookbooks is $2.09 per book plus a one-time setup fee of $349. All taxes are included. Which of the following functions models a(x), the average cost per book of printing x cookbooks?

• a(x) = 2.09x + (349/x)

• a(x) = (2.09x + 349)/x

• a(x) = (2.09 + 349)/2.09x

• a(x) = (2.09x + 349)/2.09x

There were 417 cell phones sold at an electronics store in January. Since then, cell phone sales at this store have increased at a rate of 3.75% per month. At this rate of growth, which function can be used to determine the monthly cell phone sales m months after January?

• p(m) = 417(0.0375)^m

• p(m) = 417(1.0375)^m

• p(m) = 417(0.9625)^{(m + 1)}

• p(m) = 417(0.0375)^{(m + 1)}
