I use box method to solve this...:
100x^2+34x+49
I hope you wanted the formula! :)
Yes! There is one output and one input, which is the definition of a function. You can also graph the function and test for the vertical line test. Graph a few points, connects the dots. Draw a vertical line through the graph and if the vertical line passes through the graph more than once, it is not a graph.
Here is the answer to your question. I wasn’t sure what number to round to, so I had three places.
Answer: The selling price of the coffee maker is $92.04
If the original cost is $76.70 but the company wants to make profit from the product, meaning they want to sell it higher than what they purchased it for in order to gain money, then you add the markup cost to the original cost (20%).
$76.70 + 20% of $76.70
=$76.70 + $15.34
=$92.04 selling price of coffee maker.
