Question

1. 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.
Answer:

Answer 1

wait... first one is C = 30 +10(d-1) plug in 5 for value of d

Answer 2

second one is 2x + 3y +2x -2y -3x
grouping like terms you have: x + y :)
