Question 214386
If the temperature for a 24 hour period ranged between 41 and 59 (degrees Fahrenheit, what is the range in Celsius degrees? Use the formula F=(9/5)C+32. Epress the answers as a compund inequality.
----------------------------------
41 < (9/5)C + 32 < 59
---
Subtract 32 along the line:
9 < (9/5)C < 27
---
Multiply thru by (5/9) to get:
5 < C < 15
