We know that :
⊕ Sum of the interior angles in a Pentagon should be equal to 540°
⇒ x° + (2x)° + (2x)° + 90° + 90° = 540°
⇒ (5x)° = 540° - 180°
⇒ (5x)° = 360°

⇒ x° = 72°
The rule (x, y) ⇒ (x-2, y+3) will translate the way you want.
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;
