Question

At a gourmet nut shop, nuts are sold in bulk. Cashews sell for $1.30 per pound and macadamia nuts sell for $8.45 per pound. Lee wishes to purchase 5 pounds of mixed nuts by mixing 3.5 pounds of cashews and 1.5 pounds of macadamia nuts. What will be the price per pound of the mixture?

Answer 1

To find the total price of Lee's nut mixture, you will need to calculate 

 

(pounds of cashews x price of cashews) + (pounds of macadamias x price of macadamias)

 

This tells you exactly how much he will spend. To further calculate the average price per pound of Lee's mixture, you must divide the sum of the values in parentheses by the total amount of nuts purchased (i.e. 5 pounds)
