A plant food is made from three chemicals The combined amounts must be 70 percent of the resulting mix The second and third must be in the ratio of 5 to 4 by weight How much of each chemical is needed?
To find the amount of each chemical needed, let's assume the weights of the second and third chemicals are 5x and 4x, respectively. Since the second and third chemicals must be in a 5:4 ratio, their weights will be 50% and 40% of the total mix, respectively. This means that if the total mix is 100 units, the weights of the second and third chemicals are 50 units and 40 units, respectively. This leaves 10 units for the first chemical, making the amounts needed to be 10 units for the first chemical, 50 units for the second chemical, and 40 units for the third chemical.

Start by finding the area of the entire brownie. Area = Length x Width. Both Length and Width are '5' in this case. 5 x 5 = 25 The area of the ENTIRE brownie is 25. You're trying to find the area of each piece, so you divide 25 (the area) by 2 (2 halves of the brownie). 25 divided by 2 = 12.5 Therefore, each brownie half is 12.5
