How many pounds of each kind of nut did he buy?

Question

JB bought 5 pounds of nuts for a party, including salted almonds and pecans. He
paid a total price of $61.95, with the price of almonds at $17.99/lb. and the price
of pecans at $9.99/lb. How many pounds of each kind of nut did he buy?

Answer 1

a + p = 5

17.99a + 9.99p = 61.95

 

a = 5 - p (or p = 5 - a)

 

17.99(5 - p) + 9.99p = 61.95

 

Solve for p, then plug your value for p back into the first equation and solve for a.
