The cost of a parking permit consists of a one-time administration fee plus a monthly fee. a permit purchased for 12 months cost
julsineya [31]

let

x--------> the monthly fee

y--------> the administration fee

we know that

660=y+12x --------> equation 1

810=y+15x --------> equation 2

Multiply by -1 equation 1

-660=-y-12x ------> equation 3

Adds equation 2 and equation 3

810=y+15x\\-660=-y-12x\\---------\\   810-660=15x-12x\\ 3x=150\\ x=50\ dollars

Find the value of y

660=y+12x\\ 660=y+12*50\\ y=660-600\\ y=60\ dollars

therefore

the answer is

the administration fee is equal to 60\ dollars
