: 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 100lb of mixture that will sell for $11.25 per pound. How much of each type of bean should be used in the mixture? This question is from textbook
You can put this solution on YOUR website! x = pounds of $9 beans
y = pounds of $12 beans
together they add up to 100 pounds
x + y = 100
(income from sales of $9 beans) + (income from sales of $12 beans) = total income
total income = (total pounds of mixture) x (price per pound of mixture)
multiply the 2nd equation by 9 and subtract from the 1st pounds of $12 beans to be sold pounds of $9 beans to be sold
