• It costs 9 per day to enter MathLand. There is a
  one-time entrance fee of 35.
• Write an equation for the total cost, C(n), as a
  function of the number, n, days you visit.
• b) You spent 170. How long did you stay?

C(n) 9n 35
C(n) 9n 35 170 9n 35 135 9n n

C(n) 170 n ?
If you spent 170 at MathLand, it means you
spent 15 days there!!

• Use your calculator to find the line of best fit.
• Using the equation from above, estimate x when y
  is 113.

1) y -3.02x 67.28

• 113 -3.02x 67.28
• 45.68 -3.02x
• x 15. 13
