Answer:
Weight of nuts = 6 pounds.
Weight of cereal squares = 6 pounds.
Step-by-step explanation:
Let the weight of nuts used in the trial mix to be x pounds and the weight of cereal squares used in the trial mix to be y pounds. Total weight of the mixture is 12 pounds. Therefore: x + y = 12. This implies y = 12 - x (Equation 1).
Cost of nuts per pound = $8 and cost of cereal squares per pound = $3. Cost of the mixture per pound = $5.5. Total mixture = 12 pounds. Since x pounds of nuts and y pounds of cereal squares are used, therefore: 8x + 3y = 5.5 * 12.
8x + 3y = 66. (Equation 2).
Put equation 1 in equation 2.
8x + 3(12 - x) = 66.
8x + 36 - 3x = 66.
5x = 30.
x = 6.
Put x = 6 in equation 1.
y = 12 - 6.
y = 6.
Therefore, the weight of nuts used in the trial mix will be 6 pounds and the weight of cereal squares used in the trial mix will be 6 pounds!!!
(a) $0.06 per kilogram
(b) $0.72 per 12 kg bag
Well first you must find what 71/2 is equal to:
71 / 2 = 35.5
Now you should convert this to a decimal instead of a percent. All you have to do is move the decimal two places to the left when going from percent to decimal:
35.5% = .355
Now that you know the decimal value, you want to know what number is 12 35.5% of. To do this, think, if you were wondering what is 10% of 100, you would multiply 100 by .10 so in this case since you are going the opposite way, you would divide 12 by .335, which gives you:
35.8208955224
This can be approximated to:
≈35.82
