Hya think of a number "m" . She square it, add "y" to the answer and then subtract 7 from it. The final answer is "A". 1) Derive the formula for A 2) Using the formula, find the value of A when m= 3 and

Given, to find A we have to :

From the question, the following equation can be formed :

Therefore, the formula for finding A = m² + y - 7

The value of A we can derive from the formula is :

Value of m = 3 (given)

Which means :

Thus, the value of A = 2+y

Therefore, the value of A = 2+y

10% of increase is the final answer! : )
