Answer:
y=250x+300
Step-by-step explanation:
Let x be the number of heaters and y be the total cost.
We need to find the linear function for y in terms of x.
It is given that company can produce 15 heaters for $4050 and 25 heaters costs $ 6550.
It means the line passes through the points (15,4050) and (25,6550).
If a line passes through two points and
, then the equation of line is
The equation of line is
Add 4050 on both sides.
Therefore, the required linear function is y=250x+300.
