You budget $100 each month for parking. Each day you use the downtown parking lot. It costs $5. Write a rule to represent the amount of money left in the monthly budget as a arithmetic sequence. How much money is left in you budget after you have used the downtown parking lot 11 times this month.

M = 100  5d
M(11) = 100  5(11)
