Renting a bicycle at a local bike shop costs $30 for the first day and $10 for each additional day.
a. create a chart of values and write an equation to find the total cost, c in terms of the number of days d.
b. use the equation you created in part a to find the cost of renting a bike for 5 days.
2. simplify the following problem using the distributive property: 2x + 3y + 2(x – y) – 3x. show each step in your calculation. justify each of your steps using number properties.

Abusiness plan is centered around a circular area of distribution. the plan calls for the radius of the distribution to increase 50 miles per year. the investors have asked that the plan include a reference to the area of distribution based on the number of years in business. these functions model this plan: radius in y years: r(y) = 50y total area: a(r) = πr2; r in miles what is a(r( the total area in y years? a(r(y)) = 50πy2 a(r(y)) = 2,500πy2 a(r(y)) = 50πr2 a(r(y)) = 2,500πr2
