Andrew is preheating his oven before using it to bake. The initial temperature of the oven is 65° and the temperature will increase at a rate of 10° per minute after being turned on. What is the temperature of the oven 15 minutes after being turned on? What is the temperature of the oven tt minutes after being turned on?

Temp after 15 minutes:
Temp after tt minutes:

Temp after 15 minutes:

Since the oven temperature increases 10° per minute, after 15 minutes the temperature would have increased by 10° * 15 minutes = <<10*15=150>>150°.
Therefore, the temperature of the oven after 15 minutes would be 65° + 150° = <<65+150=215>>215°.

Temp after tt minutes:
Since the oven temperature increases 10° per minute, after tt minutes the temperature would have increased by 10° * tt minutes = 10tt°.
Therefore, the temperature of the oven after tt minutes would be 65° + 10tt°.
