The instruction manual on the industrial oven suggests your oven temperature will increase by 45 degrees Fahrenheit per minute. When the over 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.

70 + (7 * 45) = x
How do you think I arrived at this answer?
To find the temperature of the oven after 7 minutes, we can use the given information that the oven temperature increases by 45 degrees Fahrenheit per minute.
Start with the initial oven temperature of 70 degrees Fahrenheit. To determine the temperature after 7 minutes, we can simply multiply the number of minutes by the rate of increase (45 degrees Fahrenheit per minute) and add the result to the initial temperature.
So the expression to find the temperature after 7 minutes would be:
Temperature after 7 minutes = Initial Temperature + (Rate of increase × Number of minutes)
Temperature after 7 minutes = 70 + (45 × 7)
To calculate this expression, simply perform the multiplication first (45 × 7) which gives you 315, and then add that result to the initial temperature of 70.
Temperature after 7 minutes = 70 + 315
Therefore, the temperature of the oven after 7 minutes would be 385 degrees Fahrenheit.
