Ten people from a local youth group went to black hills whitewater rafting tour company for a one day rafting trip. the group paid $425.

Write an equation in slope-intercept form to find the total cost C for p people.

How much would it cost for 15 people?

42.5p=c

You get you get the number 42.5 since you know 10 people paid 425, you would divide 425 by 10 to know how much every person paid.

M is representing the amount of money each person paid

(M) 10=425

M=425/10

M=42.50 < - since it's about money

Each person paid $42.50

The cost for 15 people is $637.50.

42.5p=c

42.5 (15) = 637.5
