Answer:
y = - 
Step-by-step explanation:
Given that the quantities vary inversely then the equation relating them is
y =
← k is the constant of variation
To find k use the condition x = 4 when y = - 6
k = yx = - 6 × 4 = - 24
y = -
← equation of variation
29440 divided by 2 equals 14,720
15-6.9=8.1
8.1 x 3.9= 31.59
$31.59 is your answer
hope this helps :)
