The chief difficulty that our students seem to have in answering the questions seems to be in the calculations necessary in question 6 and 21 of Part I. These seem to arise chiefly from lack of practice in using percentages.
As percentage simply denotes the number of parts in 100, it seems simplest in this problem to calculate the cost of 1 pound of proteid in 100 pounds of each of the materials, viz., if beef contains 19% of rro-teid (table page 57), 100 pounds of beef will contain 19 pounds of proteid, and 100 lbs. beef steak @ 22c. a lb. costs $22.00. Then 1 lb. proteid in beef steak will cost $22.00/19 = $1.15 per lb. In the came way:
100 lbs. of milk with 3.3% proteid contains 3.3 lbs.
100 lbs. milk = 50 qts. @ 7c a qt. costs $3.50. 1 lb.
Proteid in milk costs $3.50/ 3.3 = $1.06 per lb.
In like manner, the cost of one pound of proteid in bread and in corn meal is obtained with little calculation and the cheapest source of proteid is obvious. In the use of percentage and decimals, to avoid errors in pointing off, note whether the answer is reasonable.
Although Question 21 is optional, - "Calculate the amount of proteid, carbohydrates, and fat in own diet for one day as nearly as you can," a number of interesting solutions have been sent in. The following is a good example:
