Question

Mary's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Mary $4.25 per pound, and type B coffee costs $5.90 per pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $353.10. How many pounds of type A coffee were used?

Answer 1

117.7

Explanation:

if you take 353.10 and divide it by three (since the blend is ⅔ B and ⅓ A, meaning you need 3 parts), you get 117.7

That means that double 117.7 should be the amount of type b and 117.7 should be the amount of type a.
