A jasmine tes sells for 7.00 per pound, and a chamomile tea sells for 5.50 per pound. How many pounds of each tea are needed to create 10 pounds of a mixture that sells for 6.40 per pound?
Answer provided by our tutors
let
j = lbs of the jasmine tea
c = lbs of the chamomile tea
we need to make 10 lbs mixture:
j + c = 10
that sells for 6.40 per pound:
7.00j + 5.50c = 6.40*10
7j + 5.5c = 64
by solving the system of equations:
j + c = 10
7j + 5.5c = 64
we find
j = 6
c = 4
