Assuming that the rate of shoe sales
is a constant, you can use two data
points to predict the June sales of
Brand A if we know the total June
sales. Use a line of best fit to find the
June sales of Brand A if the store
sells a total of 32 pairs in June.
Hint: Find y
'(32).
18 pairs of Brand A will be sold in June
if the total sales are 32 pairs.
