Answer:
Slope is positive.
Every additional hat produced results in a cost increase of $0.60
Before producing any hats the cost is about $100
Step-by-step explanation:
Calculate the slope or rate of change using two data points from the table.
[tex]m = \frac{111-105}{20-10} =\frac{6}{10}[/tex]
This means that the cost rises by $6 for every 10 hats or 0.60 per 1 hat. The slope is positive and increasing.
This also means that for 0 hats the cost is 105-6 = 99 or about $100.
