The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
Given: Joe's income in the first year is $22,900, and in the fifth year his income was $26,100.
Since Joe's income increases by the same dollar amount every year, therefore it follows an arithmetic progression(A.P) with the first term as 22,900, and the fifth term as $26100.
Let the common difference of this A.P be d. Then,
So the common difference of given A.P is 800.
