Question 321056: I have looked thru about 1000 answers on here and can't figure out how to solve my problem. Finding the slope, I came up with .20. Am I right that this means there is a .20 increase of profit per person? I feel like this should be so simple but I just can't quite come up with an equation that works. Please help!! Here is the problem: If the profit from 500 customers is $1000 and the profit from 900 customers is $3000, what will the profit be for 1500 customers?
Thanks so much!

You can put this solution on YOUR website! If the profit from 500 customers is $1000 and the profit from 900 customers is $3000, what will the profit be for 1500 customers?
-----------------
Find a linear equation that relates profit and # of customers.
---
slope = (3000-1000)/(900-500) = 2000/400 = 5
----
1000 = 5(500) + b
b = -1500
-------------------
Equation:
profit = 5(cust) - 1500
---
what will the profit be for 1500 customers?
profit = 5*1500-1500
profit = 4*1500 = $6000
