Question 1123249: a merchant mixes tea that sells for $7.20/kg and tea that sells for $9.20/kg to make 100 kg of tea that he sells for $8.80/kg. How many kilograms of each type of tea did he mix? Answer by ikleyn(52795) (Show Source):
Your equation is THIS :
Cost of one ingredient + Cost of the other ingredient = cost of the mixture, or
9.20*x + 7.20*(100-x) = 100*8.80
Simplify and solve for x, which is an amount of the $9.20/kg tea.
Then evaluate 100-x for the mass of other tea.
