Given parameters:
To solve this problem, we need follow it stepwisely.
Let the amount raised by Manny = M
amount raised by Ada = A
Now, let us go through the problem sentence by sentence and interpret it algebraically;
Algebraically;
M = 2A - 7 ----- (I)
M = A + 45 ----- (II)
Now that we have established two equations we can equate them and solve for A;
2A - 7 = A + 45
2A - A = 45 + 7
A = 52
Ada raised $52 during the fundraiser event.
