100For 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.

200A 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.

300A 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

500A 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?
