howdy, heres my problem.

Plastec makes automatic sprinkler system part for a landscaping company called evergreen systems.
the manager of plastec determinds that the set up costs will be $3500 and that each part will cost$1.80
to make. evergreen systems pays plastec $1000 to start the line of business and will pay$2.20 for each part thereafter.

using the information above I managed to determine that the cost, C, and revenue, R, equations were as follows if (n) was the number of parts made....

C = 3500 + 1.80n
R = 1000 + 2.20n

How do I find the breakeven point algebraically????

an answer and/or an explanation on how to do it would really help!
need really soon
Thanks!

$\displaystyle 3500 + 1.8 n =1000 +2.2 n$
Now you solve this for $\displaystyle n$ the breakeven number of units.
