Answer:
A 20
B The constant is $4/ square ft
Step-by-step explanation:
We can find the slope of the cooking time versus weight by
m = ( y2-y1)/(x2-x1)
= (50-30)/( 2.5-1.5)
= 20/1
The constant is the slope which is 20
For the second problem, we also need to find the slope
We have points, (0,0) and (250,1000)
m = ( y2-y1)/(x2-x1)
= ( 1000-0)/(250-0)
1000/250
4
The constant is $4/ square ft
