Question 288243: The Boxerville city council must pay three companies to have street lamps put on the 4th Street Bridge. Company M will make the lamps for $25 per lamp, plus $125 fee. Company S will install the lamps for $40 per lamp, plus $100 fee. Company P will paintthe lamps for $15 per lamp, plus a $50 fee.
Using n as the number of lamps, write a polynomial for each company that tells you how much the company will charge.
Company M? = 25n + 125?
Company S? = 40n + 100?
Company P? = 15n + 50?
find the sum of the three polynomials? = 80n + 275?
Use the sum you found to write an inequality that shows that the city council can pay no more than $3,500 total. 80n - 3225
How many street lamps can they put on the bridge for $3,500?
How many lamps can they put on the bridge for 4,300?

You can put this solution on YOUR website! The Boxerville city council must pay three companies to have street lamps put on the 4th Street Bridge. Company M will make the lamps for $25 per lamp, plus $125 fee. Company S will install the lamps for $40 per lamp, plus $100 fee. Company P will paintthe lamps for $15 per lamp, plus a $50 fee.
---------------------------------
Using n as the number of lamps, write a polynomial for each company that tells you how much the company will charge.
Company M? = 25n + 125?
Company S? = 40n + 100?
Company P? = 15n + 50?
find the sum of the three polynomials? = 80n + 275?
Use the sum you found to write an inequality that shows that the city council can pay no more than $3,500 total. 80n + 275 <= 3500
-------
How many street lamps can they put on the bridge for $3,500?
Solve: 80n+275 <= 3500
80n <= 3225
n <= 40.31
Round down to get n = 40
-------------------------------
How many lamps can they put on the bridge for 4,300?
80n+275 <= 4300
80n <= 4025
n <= 50.31
Round down to get n = 50
