that a merchant wishes to mix candy worth 45 cents per pound, with some candy that costs 80 cents per pound. this will create a mixture of candy that sells for 65 cents per pound. there is a total amount of 350 pounds of candy. What i need to know is: The amount of pounds of candy at 65 cents per pound? and The amount of pounds of candy at 80 cents per pounds? |
Adriana,
Suppose the merchant uses x pounds of candy worth 45 cents per pound then, since she uses a total of 350 pounds of candy she must use 350 - x pounds that cost 80 cents per pound.
What is the value of x pounds at 45 cents per pound?
What is the value of 350 - x pounds at 80 cents per pound?
The sum of these two values must be value of the mixture, that is the value of 350 pounds at 65 cents per pound.
Solve for x.
