I used to look at the examples i can’t remember now what it is but look at the examples
The interest rate is 3.5%.
EXPLANATION
We substitute the given values into the formula;

to obtain

We divide through by 6000 to obtain,

This implies that,

We take the square root of both sides,

This gives us,

Add -1 to both sides of the equation to obtain

Multiply through by 100 to obtain;

%
Y = k/x where k is the constant of variation
y = 3 , x = 1.2 gives
3 = k/1.2
therefore
k = 3*1.2 = 3.6
and the required equation is
y = 3.6 / x
50.55 x 1.75 = 88
45.2 x 2.25 = 94
