[Video] Q31: The graph above models the daily profit, y, in dollars, that a school club expects to make from selling shirts for a price of x dollars. based on the model, what is the maximum daily profit, in dollars? (disregard the $ sign when gridding your answer.)

Explanation for Question 31 From the Math (Calc) Section on the 2019 October Sat

Now question number 31, it tells us that the graph above shows the profit 2 in dollars. Right? So our profit is on our y-axis, 3 um, for selling t-shirts at a price of X dollars. 4 So the price of our t-shirts is on our x-axis. 5 So it's based on the model, what is the maximum daily profit? 6 Okay. So we want the maximum daily profit, 7 and we need to know for that, that the profit is on the Y 8 axis. So essentially we're looking for the max the highest point that we 9 can reach on the Y axis. And if we look at our graph, 10 we see that the highest we ever get is at 60, 11 right? 60 on the Y axis. That is our maximum. 12 And so essentially that means that our maximum profit is going to be 60.
