Amanda sells homemade birthday cakes for a profit of $39 per cake. She is considering switching to a new type of icing that will increase her profit, as expressed by the function y = 45x, where x is the number sold and y is the amount of profit.

How many more dollars will Amanda earn on each cake if she switches to the new material? Explain how you found your answer

Hey everyone! I just wanted to talk about this really cool math problem I came across. So, there's this girl named Amanda who sells homemade birthday cakes and she makes a profit of $39 per cake. But guess what? She's thinking about switching to a new icing that could make her even more money!

The new icing is supposed to increase her profit, and it's all represented by this fancy function: y = 45x. In the equation, y stands for the amount of profit and x is the number of cakes Amanda sells. Sounds pretty neat, right?

Now, the question is, how much more money will Amanda earn on each cake if she makes the switch? Well, to find that out, we just need to see the difference between the two profits. So, the profit with the new icing is represented by the equation y = 45x, and we know that Amanda's current profit is $39 per cake.

To find the difference, we subtract $39 from the new profit equation: 45x - 39. That's it! That's how we figure out how many more dollars Amanda will earn on each cake if she switches to the new icing.

I hope that makes sense and you found it as interesting as I did! Math can be pretty exciting sometimes, right?
