Yup its 8000
HOW!!! do you get the answer though!
1.15*1.10*M=10,120

To find out how much was raised two years ago, we'll need to follow these steps:
Step 1: Calculate the amount raised last year.
We know that donations to the annual fundraiser last year were 10% greater than the year before. Let's assume the amount raised two years ago was X dollars.
So, the amount raised last year would be X + (0.10 * X) = 1.10X dollars.
Step 2: Calculate the amount raised this year.
Given that donations this year are 15% greater than last year, we can write the equation as:
1.15(1.10X) = 10,120
Step 3: Solve the equation.
Let's simplify the equation and solve for X:
1.265X = 10,120
X = 10,120 / 1.265
X ≈ 8,000
Therefore, approximately $8,000 was raised two years ago.
