NTACT JOBS VOLUNTEER PEOPLE 23-28: Linear Equations. The following situations can be modeled by inear functions. In each case, write an equation for the linear function and use it to answer the given question. Be sure you clearly identify the independent and dependent variables. Then briefly discuss whether a inear model is reasonable for the situation described. 23. The price of a particular model of car is $18,000 today and rises with time at a constant rate of $900 per year. How much will a new car of this model cost in 3.5 years? 24. In 2016, Katy Ledecky set the women's world record in the 800-meter freestyle (swimming) with a time of 8.04.79, or 8 minutes 4.79 seconds. Assume that the record time falls at a constant rate of 1. 15 seconds per year (which was the aver- age rate from 2008 to 2016). What does the model predict for The record time in 20247 (Hint: Convert the 2016 record time of 8:04.79 into seconds before writing your equation.) 25. A snowplow has a maximum speed of 40 miles per hour on a dry highway. Its maximum speed decreases by 1.1 miles per hour for every inch of snow on the highway. According to this model, at what snow depth will the plow be unable to move? 26. The cost of leasing a car is $1000 for the down payment and processing fee plus $360 per month. For how many months ate of can you lease the car with $3680? ne vari- merically 27.
