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.
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.

Answer: y = 7.5
Step-by-step explanation:
Suppose that y varies directly with x
That is, y∝x
Convert y∝x to a full equation by introducing a constant k to the right hand side.
Therefore, y = kx
Given that y = 10 and x = 20
Substitute y and x in the equation above. We have;
10 = k(20)
10 = 20k
20k = 10
k = 10/20
k = 0.5
Since k = 0.5, the equation y = kx becomes y = 0.5x
Now, to find y if x = 15, substitute x in equation y = 0.5x
Therefore, y = 0.5(15)
y = 7.5
