2.You are trying to decide how to most efficiently use your oven. You do not want the oven running at a high temperature when it is not baking, but you also do not want to waste a lot of time waiting for the oven to reach the desired baking temperature.

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.

3.In your industrial oven, you bake two baking sheets with 12 scones each, two baking sheets with 20 cookies each, and one baking sheet with 2 scones and 10 cookies.

a)Write an expression that illustrates the total cost of all baked goods in the scenario above using the variable s to represent the cost of scones and the variable c to represent the cost of cookies. Simplify your expression by combining like terms.

b)Suppose you have decided to price the scones at $2.28 each and the cookies at $1.19 each. How much total revenue would result from selling all the scones and cookies baked in the oven at one time?

c)Yesterday your store earned $797.30 just from the sale of cookies. Write and solve an equation that represents how many cookies were sold.

We will be happy to critique your thinking.

2. To find the temperature of the oven after 7 minutes, we can use the given information that the temperature increases by 45 degrees Fahrenheit per minute.

We start with the initial temperature of 70 degrees Fahrenheit. In 7 minutes, the temperature would have increased by 7 * 45 = 315 degrees Fahrenheit.

To find the final temperature, we add the temperature increase to the initial temperature:

Final Temperature = Initial Temperature + Temperature Increase = 70 + 315 = 385 degrees Fahrenheit.

So, the temperature of the oven after 7 minutes would be 385 degrees Fahrenheit.

3a. To find the total cost of all baked goods, we need to calculate the cost of each type of baked good separately and then add them together.

The cost of the two baking sheets with 12 scones each would be 2 * 12 * s = 24s.

The cost of the two baking sheets with 20 cookies each would be 2 * 20 * c = 40c.

The cost of the baking sheet with 2 scones and 10 cookies would be 2 * s + 10 * c = 2s + 10c.

To calculate the total cost, we add these three amounts together:

Total Cost = 24s + 40c + 2s + 10c.

Simplifying the expression by combining like terms, we get:

Total Cost = 26s + 50c.

So, the expression that illustrates the total cost of all baked goods is 26s + 50c.

3b. If the scones are priced at $2.28 each and the cookies at $1.19 each, we can find the total revenue by multiplying the price per item by the number of items for each type of baked good and then summing them up.

The revenue from the two baking sheets with 12 scones each would be 2 * 12 * $2.28 = $54.72.

The revenue from the two baking sheets with 20 cookies each would be 2 * 20 * $1.19 = $47.60.

The revenue from the baking sheet with 2 scones and 10 cookies would be 2 * $2.28 + 10 * $1.19 = $4.56 + $11.90 = $16.46.

To find the total revenue, we add these three amounts together:

Total Revenue = $54.72 + $47.60 + $16.46 = $118.78.

So, the total revenue from selling all the scones and cookies baked in the oven at one time would be $118.78.

3c. Let's assume the number of cookies sold is represented by the variable x. We know that the total revenue earned from cookie sales yesterday was $797.30.

If we multiply the number of cookies (x) by the cost per cookie ($1.19), it should equal the total revenue earned:

x * $1.19 = $797.30.

To solve for x, we divide both sides of the equation by $1.19:

x = $797.30 / $1.19.

Evaluating the division, we find:

x = 670.

So, 670 cookies were sold yesterday.
