1. A coffee merchant has coffee beans that sell for $9 per pound and $12 per pound. The two types are to be mixed to create 100 lb of a mixture that will sell for $11.25 per pound. How much of each type of bean should be used in the mixture?

Hello, Patience,
let x be the amount of the cheaper coffee
let y be the amount of the more expensive coffee
then you get a system of simultanous equations:
A: x + y = 100
B: 9x + 12y = 11.25 * 100
I don't know which method you use to solve this system but you should get the results:
x = 25 and y = 75
