Explanation:

Step1: Find slope of best fit

Use points $(0,104)$ and $(36,62)$:
$$m=\frac{62-104}{36-0}=\frac{-42}{36}=-\frac{7}{6}$$

Step2: Write line equation

Y-intercept $b=104$, so:
$$y=-\frac{7}{6}x + 104$$

Step3: Substitute $x=54$

$$y=-\frac{7}{6}(54) + 104$$

Step4: Calculate the value

$$y=-63 + 104=41$$

Answer:

41 hot cocoas
