Question

I could use some help with these two problems. I also need help with my question before this one.

Option #1: Annual club membership at a fee of $125 per year plus an option of prepaying for unlimited music downloads at a rate of $10 per month.

1. Write a function that best models the total cost of club membership plus downloads under option #1.

2. For membership option #1, calculate the total cost for one year of club membership and prepaid unlimited music downloads.

Answer 1

1. a one time fee of $125 plus $10 per month for downloads

c = total cost

m = number of months

 so equation would be c = 125+10m

2. 1 year = 12 months

 so you get c = 125+10(12)=

c = 125 +120

c = $245
