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
Explanation:
Calculate the slope or rate of change using two data points from the table.
![m = (111-105)/(20-10) =(6)/(10)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8hgk3kguuquwkknaqk61aeunc9ittcuvrg.png)
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.
