: Can someone help me on this problem?
I need to solve the following problem and show the equation used for the solution:
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?
Thanks,

You can put this solution on YOUR website! Let a = amount of the $9/pound beans in mixture (in pounds)
Let b = amount of the $12/pound beans in mixture (in pounds)
a + b = 100 (this is given)
Set up this equation:
This simply says "The cost of a pounds of the $9 beans plus
the cost of b pounds of the $12 beans per 100 pound bag must
equal $11.25 per 1 pound." (given) (multiply each side by 12)
Now subtract the 1st equation from the second (amt of the %9 beans to use) (amt of the $12 beans to use)
check
do the math- checks OK
