A Function is defined as the relation between the input and the output where one input can have only one output
When graphing functions, the x-axis denotes the inputs and the y-axis denotes the output of the function
Looking at the graph, we see that for one input (point on the x-axis) we have only one output (point on the y-axis)
Hence, we can say that this graph represents a function
Answer:
The prices at which manager predict that at least 55 hats will be sold would be would be of $38
Step-by-step explanation:
According to the given data we the following:
Number of hats sold at $18=115
The manager predicts at 3 less will sold for every rise in 1 $ for at least 55 hats.
Therefore, reduction in number=115 hats-55 hats=60
So, increase in price=reduction in number/number of hats manager predicts that will be sold for every $1 increase in price
increase in price=60/3=$20
Therefore, prices at which manager predict that at least 55 hats will be sold would be=$18+$20=$38
The prices at which manager predict that at least 55 hats will be sold would be would be of $38
