Answer:
y =
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = when x =
, thus
=
= 2k ( divide both sides by 2 )
k =
y = ← equation of variation
When x = , then
y = =
=
Answer:
The total cost is D) $141
Step-by-step explanation:
To solve we can use the equation:
d= number of days m= number of miles
We know both of these values so we can plug them in and solve.
y= 25(3) + 0.10(660)
y= 75 + 66
y = 141
