124. Grain is generally priced by the bushel, but sold by the pound.

1. Find the value of 24000 lb. of wheat at 95¢ per bushel.

$240, value at 60¢ per bushel 120, value at 30¢ per bushel

20, value at 5¢ per bushel $380, value at 95¢ per bushel

There are 60 lb. in a bushel of wheat; then 60% per bushel would be 1o per pound. Point off two places in the number of pounds to find the value at 60% per bushel $240. of $240 would give the value at or 30 per bushel; would give the value at or 5 per bushel.

of 60%,

of $120

of 30%,

2. What is the value of 24000 lbs. of coal (retail) at $8 per ton?

Point off 3 places to show the number of thousands of pounds. Multiply by the price, for $8 per ton is $4 per 1000 pounds.

3. Extend and foot the following bill of feed:

125. A graph is a diagram showing fluctuations, such as variations in temperature, rise and fall of prices, etc.

The temperature chart shows variations in temperature from 6 A.M. to 6 P.M. The hour is indicated by the row

of figures along the top; the temperature is indicated by the vertical column at the left.

Illustrate graphically:

1. The varying price of wheat for the years 1900 to 1911, the prices for the respective years being as follows: 1900, 611; 1901, 631; 1902, 671; 1903, 701; 1904, 811; 1905, 77; 1906, 691; 1907, 71; 1908, 8410; 1909, 991; 1910, 891; 1911, 831¢.

1904, 2467; 1905, 2707; 1906, 2927; 1907, 2592; 1908, 2668; 1909, 2772; 1910, 3125.

TO THE PUPIL. On a sheet of graph paper keep a daily record, after your work has been checked in class, of problems solved correctly.

Problems missed should be worked after they have been explained in class. Then, by means of a dotted line, indicate the percentage of problems so corrected. This line should not show much variation.
