Answer:
B
Step-by-step explanation:
Since p and v vary inversely then the equation relating them is
p =
← k is the constant of variation
to find k use the condition p = 8 when v = 40
k = pv = 8 × 40 = 320
⇒ p(v) =
→ B
1. You have that a<span> student's pay of $18 an hour </span>is <span>$4 more than twice the amount the student earns per hour at an internship.
2. So, let's call the </span><span>hourly pay of the internship: "x". Then, you have:
</span><span>
18=2x+4
3. When you clear the variable "x", you obtain:
18-4=2x
14=2x
x=14/2
x=$7
Therefore, the answer is: T</span><span>he hourly pay of the internship is $7.</span>
