Question 951382: Please help!
At the local grocery store, apples are $1.20 per pound and oranges are $1.80 per pound. If the grocer wants to offer a 1.4-pound bag of mixed fruit for $1.62 per pound, how many pounds of apples must he use?
Answer by josgarithmetic(39617) About Me  (Show Source):
You can put this solution on YOUR website!
x, how many pounds apples.
1.4-x, how many oranges.
The two-part mixture problem can be handled in one variable.

Now just account for price.
%281.2x%2B1.8%281.4-x%29%29%2F1.4=1.62
Simplify and solve for x.

You could also start this using two variables. For that, you could see the lesson http://www.algebra.com/my/mixture-price-two-part-both-parts-unknown.lesson?content_action=show_dev
