Question 604601
it is a system of equations that you solve by substitution or elimination


125m + 70c = 255 ___ multiplying by 2 ___ 250m + 140c = 510


3m + 4c = 24.6 ___ multiplying by 35 ___ 105m + 140c = 861


subtracting the equations will eliminate c


solve for m, and substitute back to find c
