A group of people are buying a gift for a friend. They decided to split the cost of a $100, and also get their own $5 item to put in the basket. Write an equation to model how much each person will have to pay for the present. (Use x as the number of people and y as the total cost)

• y=(100+5x)/x

• y=(100x+5)/x

• y=100/x

You start a business of typing papers for other students. You spend $2500 on a computer system and printer. You are charging $0.02 per page. Write an equation to show the cost per person you should charge.

• y=(2500+0.02x)/x

• y=(2500x+0.02)/x

• y=2500+0.02x

What is the horizontal asymptote of the function given?

• y = 2

• x = 1

• x = 2

• y = 1
