Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Chapter P.5, Problem 72E

E-Filing The table shows the numbers of tax returns (in millions) made through e-file from 2007 through2014. Let f (t) represent the number of tax returns made through e-file in the year t.

Chapter P.5, Problem 72E, E-Filing The table shows the numbers of tax returns (in millions) made through e-file from 2007 , example 1

(a) Find f 2014 − f 2007 2014 − 2007 and interpret the result in the context of the problem.

(b) Make a scatter plot of the data.

(c) Find a linear model for the data algebraically. Let N represent the number of tax returns

made through e-file and let  t =   7 correspond to 2007.

(d) Use the model found in part (c) to complete the table.

Chapter P.5, Problem 72E, E-Filing The table shows the numbers of tax returns (in millions) made through e-file from 2007 , example 2

(e) Compare your results from part (d) with the actual data.

(f) Use a graphing utility to find a linear model for the data. Let x =   7 correspond to 2007.

How does the model you found in part (c) compare with the model given by the graphing

utility?
