Question 742077
m for the kilograms of mint candies
c for the kilograms of coffee candies
M for amount of mixture, 10 kg.
L = 75 pesos per kg, for the mint candies
H = 80 pesos per kg, for the coffee candies
T = 78 pesos per kg, TARGET price of the mixture

QUESTION: How many kg. of mint were used?  (Find m).


EQUATIONS:

{{{(mL+cH)/M=T}}}  and  {{{m+c=M}}}
Solve the system for m, entirely in given values as a formula which does not distinctly show c.  Suggested method could be to solve for c in the M equation and substitute this formula into the rational equation and solve the rational equation for m.


Use this resulting formula for m and substitute the given values to compute or evaluate m.
