You have two summer jobs. You mow lawns for $20.00 per hour. You also work at a restaurant for 7.50 per hour. In one week you earn 825.00 working 50 hours. Write an equation that can be used to find the hours that you mowed lawns.
------------------
Equations:
L + R = 50
20L + 7.50R = 825 dollars
-----------------------------------
Substitute to get an equation in "L".
---
Since R = 50-L you get:
20L + 7.50(50-L) = 825
-----------------------------
