Answer:
y=4x
Step-by-step explanation:
it's enough to use first column (x=6, y=24). Inserting this data into equation y=kx, we can calculate k.
24=k*6
6k = 24
k = 24/6
k = 4
Answer:
50
Step-by-step explanation:
The cost of the visit to the dentist can be expressed as the cost equals 100x+50.
The initial cost of the appointment would be $50; no matter how many cavities one has, they would still have to pay $50.
The cost of each cavity is represented as 100x, because each cavity costs $100. x represents the number of cavities, as we do not know how many cavities there are.
