The formula R = -0.075t+3.85 can be used to predict the world record in the 1500 meter run, t years after 1930. Determine an inequality that identifies the years in which the world record will be less than 3.1 minutes.
Solve for the t
----------------------------
-0.075t+3.85 < 3.1
-0.075t + 0.75 < 0
0.075t > 0.75
t > 10
Inequality: year > 1940
=============================
