Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition that x = 9 when y = 15
15 = ( multiply both sides by 9 )
k = 135
y = ← equation of variation
What percent - x / 100
of - * multiply
50
is - = equals
75
50x = 7500
x=150
150% of 50 is 75.
