Pharmacists For the years 2008 through 2013, the average salaries y (in dollars) of pharmacists in the United States are shown in the table. (Source: U.S. Bureau of Labor Statistics)

Year 2008 2009 2010
Salary 104,260 106,630 109,380
Year 2011 2012 2013
Salary 112,160 114,950 116,500

Spreadsheet at LarsonAppliedCalculus.com

A model for these data is given by

y = 86 , 827 ( 1.0233 ) t where t represents the year, with t   = 8 corresponding to 2008.

(a) Compare the actual salaries with those given by the model. How well does the model fit the data? Explain your reasoning.

(b) Use a graphing utility to graph the model.

(c) Use the zoom and trace features of the graphing utility to predict the year during which the average salary of pharmacists will reach $130,000.

(a)

To determine

To calculate: The actual salary with given model y=86,827(1.0233)t fits the data where t=8 corresponds to 2008 and compare actual salaries with the data of average salary of pharmacist in United States are shown in below,

Year 2008 2009 2010 2011 2012 2013
Salary 104,260 106,630 109,380 112,160 114,950 116,500

Explanation of Solution

Given Information:

The provide model is y=86,827(1.0233)t and t=8 corresponds to 2008 for the table:

Year 2008 2009 2010 2011 2012 2013
Salary 104,260 106,630 109,380 112,160 114,950 116,500

Consider the provided model y=86,827(1.0233)t, t=8 corresponds to 2008 for the tables:

Year 2008 2009 2010 2011 2012 2013
Salary 104,260 106,630 109,380 112,160 114,950 116,500

Substitute t=8 in the equation y=86,827(1.0233)t,

y=86,827(1.0233)8104,395

Substitute t=9 in the equation y=86,827(1.0233)t,

y=86,827(1.0233)9106,827

Substitute t=10 in the equation y=86,827(1.0233)t,

y=86,827(1.0233)10109,316

Substitute t=11 in the equation y=86,827(1

(b)

To determine

To graph: The model y=86,827(1.0233)t using a graphing utility.

(c)

To determine

To graph: The model y=86,827(1.0233)t using a graphing utility and use the zoom and trace feature to predict the year during which the average salary will reach $130,000.
