=__//**10/7/13 **//__= ==At a candy shop, plain candy covered chocolate costs $2.95 per pound, while candy covered chocolate with almonds costs $4.95 per pound. How many pounds of plain candy covered chocolate should be mixed with 3 pounds of candy covered chocolate with almonds to obtain a mix that sells for $3.95 per pound? How many total pounds of candy will be in the mix? ==

per pound || x pounds || 2.95x || per pound || (x+3) pounds || 3.95x + 11.85 || Equation(see final column): 2.95x +14.85 = 3.95x + 11.85 Solve for x: x=3 Answer: You will need 3 pounds of plain candy. You will have 6 pounds in the final mix.
 * $2.95
 * $4.95per pound || 3 pounds || 14.85 ||
 * $3.95

A recent experiment is trying to reduce the amount of copper sulfate in an organic crystal blend. The experiment calls for a 25% solution of copper sulfate. William has 20 milliliters of 35% solution and some of a 15% solution. How many milliliters will be in the final 25% solution? ==
 * || PERCENT OF COPPER SULFATE || MILLILITERS || TOTAL ||
 * SOLUTION 1 || 35 || 20 || (35)(20) =700 ||
 * SOLUTION 2 || 15 || X || 15(X) = 15X ||
 * MIXTURE || 25 || 20 + X || 25(20+X)=500 + 25X ||

<span style="font-family: 'Comic Sans MS',cursive;">EQUATION IS 700+15X=500+25X <span style="font-family: 'Comic Sans MS',cursive;">X=20 THEREFORE YOU WILL HAVE __//**40 MILLILITERS**//__ IN THE FINAL SOLUTION!
