Question

A store mixes Brazilian coffee worth $10 per kilogram and Turkish coffee worth $12 per kilogram. The mixture is to sell for $11 per kilogram. Find how much of each should be used to make a 468 kilogram mixture

Answer 1

10*(# of Brazillian Kilos) + 12 * (# of Turkish kilos) = Cost

Lets call the "# of Brazilian kilos" the letter "B"
and "# of turkish kilos" the letter "T"
So:
10*B + 12*T = Total Cost
and
Total Cost = 11 * 468

Also
B + T = 468

Solve for B and T

Answer 2

10B+12T=11*468
10B+12(468-B)=11*468
10B+12*468-12B=11*468
12*468-11*468=12B-10B
B=234

Answer 3

For this one however, because they chose a price that is exactly halfway between the two prices, the proportions of the two coffees will be 50/50. So half the mixture will be Brazilain and half will be Turkish.
