a tea mixture was made from 40 pounds of tea costing $5.40 per pound and 60 pounds of tea costing $3.25 per pound. find the cost of the tea mixture

Answer 1

40(5.4) + 60(3.25) = (40+60)M where M is the cost per pound of the Mixture

216 + 195= 411= 100M

M = 411/100 = $4.11 per pound of tea mixture

60 is 3/5 of 100

40 is 2/5 of 100

(2/5)(5.4) + (3/5)3.25) = 2.16 + 1.95 = 4.11
