Question 1167880: David's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs David $4.75 per pound, and type B coffee costs $5.95 per pound. This month, David made 155 pounds of the blend, for a total cost of $846.65. How many pounds of type A coffee did he use?
Let x be the value under the question.
Then you have this total money equation
4.75x + 5.95*(155-x) = 846.65 dollars.
From the equation
x = = 63.
