y = 1.5
Step-by-step explanation:
Given y is inversely proportional to , then the equation relating them is
y = β k is the constant of variation
To find k use the condition when x = 8, y = 2 , then
2 = = = ( multiply both sides by 3 )
6 = k
y = β equation of variation
When x = 15, then
y = = = = 1.5
