Question

ee ann wants to mix tea with 2 Cents per oz with 100oz of tea worth 5 cents per oz to make a mixture worth 3 cents per oz. how much 2 cent tea should be used?

Answer 1

x = number oz of cheaper tea
.02x = value of cheaper tea
100 = number oz of better tea
.05 * 100 = 5.00 = value of better tea
.03 = value of mixture
.03(x + 100) = value of mixture

.02x + 5.00 = .03(x + 100)
.02x + 5.00 = 3.00 + .03x
2.00 = .01x
x = 200

200 oz of .02 tea

Answer 2

from above
.03 = value of mixture

this should be
x + 100 = mixture total number of oz
