A mixture of 650 nails costs $43.50. If some of the nails cost 5 cents a piece, and therest costs 7 cents a piece, how many of each are there?
So the total number of nails is 650, therefore: X + Y = 650, and 5X + 7Y = 4350 First we can solve the first equation for Y: Y = 650-X Now that we know the relationship between X and Y, we can solve for one of them by substituting that value into the other equation. : 5X + 7Y = 4350 5X + 7(650-X) = 4350 5X + 4550 - 7X = 4350 -2X + 4550 = 4350 -2X=-200 X=100 Since Y = 650-X, Y = 550. If we plug those numbers into our original equations then we can verify the solution: 7(550) + 5(100) = 4350. (550) + (100) = 650
