For exercise, you swim several times a week.
Currently, you swim 5 laps each time you swim.
You want to gradually increase the number of
laps each time you swim. Your plan is to swim 2
additional laps each time you swim. Write an
equation that gives the total number of laps you
swim as a function of the number of times you
have been swimming since you started adding
laps. Find the total number of laps you will swim
in 8 weeks if you swim 3 times a week.

A printing shop charges $50 to set up its
equipment to print flyers. If the order is less than
1000 flyers, the shop charges $.45 to print each
flyer. If the order is 1000 flyers or more, the shop
charges $.30 to print each flyer. Write an equation
that gives the total cost (in dollars) for printing less
than 1000 flyers as a function of the number of
flyers printed. What is the domain of the function
from part? Explain. Use the equation to determine
how many flyers you can have printed for $400.

You are scheduled to start your job at a
car wash 2 hours after the car wash
opens. Three hours after you start, a
total of 47 cars have been washed
since the car wash opened. Three

A newspaper charges a flat rate to place a 3-line ad
in the classified section of the newspaper and then
charges a per line fee for any additional lines. One
person paced a 4-line ad for $17.10 and another
person placed a 6-line ad for $22.50. Write an
equation that gives the total cost (in dollars) as a
function of the number of lines in the ad. What to
the rate of change and the initial value in your
equation represent?
