The instruction manual on the industrial oven suggests your oven temperature will increase by 45 degrees Fahrenheit per minute. When the oven is initially turned on, the temperature is 70 degrees Fahrenheit. What will the temperature of the oven be after 7 minutes? Write an expression and explain how you arrived at your answer. Temp=70+7*45=385; I took 70 and added 7 then I took and multiplied it by 45 to get 385 degrees. Is this right?

**Noether**, Sunday, February 1, 2009 at 4:04pmThat's correct. I think it might be better if you made it clearer in your explanation that you did 70 + (7*45); as it stands now, somebody reading the explanation might think you meant you did (70+7) * 45.
