Question 1050901: A scientist measures the change in the temperature of a chemical solution. At the start of the experiment, the solution is at a temperature of -14.96 degree Celsius. The temperature decreases 2.9 degree Celsius each hour. Write an expression that can be used to find the temperature of the solution after 3 hours and what is the temperature of the solution after 3 hours rounded to the nearest whole degree? Thanks!

You can put this solution on YOUR website!
Let +T+ = the current temperature
Let +t+ = number of hours after start of experiment
+T+=+-14.96+-+2.9t+
Given: +t+=+3+
+T+=+-14.96+-+2.9%2A3+
+T+=+-14.96+-+8.7+
+T+=+23.66+
24 degrees rounded to nearest whole degree
