- Use the graph below, whichshows the minimum wages in the United States (indollars) from 1950 through 2015. (Source: U.S.Department of Labor) (a) Which decade shows the greatest increase in theminimum wage?(b) Approximate the percent increases in the minimumwage from 1985 to 2000 and from 2000 to 2015.(c) Use the percent increase from 2000 to 2015 topredict the minimum wage in 2030.(d) Do you believe that your prediction in part (c) isreasonable? Explain.arrow_forwardCar Loansa. Explain why the monthly payment P is a linearfunction of the amount borrowed A.b. Find f (25,000) and interpret its meaning.c. If f (A) = 358.49, what is A?arrow_forwardMortgage Delinquencyes The percentage of borrowers in the highest riskcategory who were delinquent on their payments decreased from 9.7%in 2001 to 4.3% in 2004 and then shot up to 10.3% in 2007.57 Model this percentage P as a piecewise-linear function of the time tin years since2001, and use your model to estimate the percentage of delinquentborrowers in 2006.arrow_forward
- After discontinuing all advertising for a tool kit in 2010, the manufacturer noted that sales began to drop according to the model 500,000 1+0.2e where S represents the number of units sold and t represents the year, with t= 0 corresponding to 2010 (see figure).

Activate The graph represents an object that is shot upwards from a tower and then falls to the ground. The independent variable is time in seconds and the dependent variable is the object's height above the ground in meters. Y A 100 90 80 70 60 30 20 10 time (seconds) 1. How tall is the tower from which the object was shot? 2. When did the object hit the ground? 3. Estimate the greatest height the object reached and the time it took to reach that height. Indicate this situation on the graph. height (meters)arrow_forwardSuppose that someone deposits $8000 in an account that earns 8.0% simple interest. Complete parts (a) and (b) below. a.
