3.) Time on a treadmill. After 2 minutes on a treadmill, Jenny has a heart rate of 82. After 3 minutes she has a heart rate of 86. Assume that there is a linear equation that gives her heart rate (h) in terms of time on the treadmill ( t ). Find the equation and use it to predict her heart rate after 10 minutes on the treadmill.

4.) If you earned an average of \$25,000 over your working life and you retire after 2005 at age 62,63, or 64, then your annual social security benefit will be 7000, 7500, or 8000, respectively. There is a linear equation that gives the annual benefit (b) in terms of age (a) for these three years. Find the equation.
