Answer:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = 
← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = 
( multiply both sides by 8 )
56 = k
P = 
← equation of variation
When x = 7 , then
P = 
= 8
Answer:
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.

$4.7 × 915 = 4300.5
$4300.5 + 79.15 = 4379.65
15% of 4379.65 = 656.9475
4379.65 + 656.9745 = 5036.6245
