Answer:
3
Step-by-step explanation:
Since y is directly related to x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 81 when x = 27
k = = = 3
Answer:
-2/6. hope this helps
Step-by-step explanation:
The equation for the total amount charged is y = 60 + 45x
<h3>How to create the equation?</h3>
The given parameters are:
Rate = $60 per service
Installation = $45
Let y represents the total charges and x represents the number of services.
So, we have
y = Installation + Rate * x
This gives
y = 60 + 45 * x
y = 60 + 45x
