1. ## [SOLVED] Systems of Equations - Work Related

Good morning/afternoon everyone!

I am actually trying to figure out the below problem as it relates to my position at work.

I have the below two equations:

P = 3X + 1.5Y
C = X + Y

X= Labor
Y = Material Cost

I know that P = 202.50.

I am trying to use all of the above information to figure out what C is (I need the numeric value, not another equation with variables in it).

I have tried multiple methods all morning and I feel as though I am missing something. Is it even possible to figure out C without at least knowing the value of either X or Y? In this case I do NOT. The only information that I do have is listed above.

Any help would be EXCELLENT! Thank you very much!
