500With a minimum purchase of $100, you
can open a credit account at a music store. The store is offering either $25 or
20% off your purchase if you open a credit account. You make a purchase of
$135 and decide to open a credit account. Should you choose $25 or
20% off your purchase? Write a system of equations and graph them to solve.

400During the spring and summer, you do a
spring yard cleanup for households and you also paint houses. You earn $8 an hour doing the cleanups and
$12 an hour painting. Last spring and summer you worked a total of 400
hours and earned $3800. How many hours did you spend doing yard
cleanups and painting?
500You are creating a potting mix for your window boxes that is 20% peat moss and
80% potting soil. You add 100% potting soil to your mix that is currently 50% peat moss and 50% potting soil. You have 4 buckets
of the mix that is half and half. Do you have enough of the half and half to make 8
buckets of the mix that is 20% peat moss and 80% potting soil? Explain.

5y – 10x = -50
500A car rental company charges a daily rental fee plus a per mile fee over 150 miles. Two different people rent the same style of car for the same number of days. The total bill for one person’s rental is $207.50 for a 5-day rental and 180 miles. The total bill for the other person’s rental is $212.50 for a 5-day rental and 200 miles.a. Write a linear system that you can use to find the
daily rental fee and the per mile fee over 150 miles. Explain how you got your linear system.
b. What is the daily rental fee? What is the fee per mile over 150 miles?
