Question

A group of students held a fundraiser last year and raised $950 for charity. This year, they raised $1,045.

What is the percent change in the amount the group raised?

Answer 1

To calculate the percent change in the amount raised by the group of students, we can use the following formula for percent change:

\[
\text{Percent Change} = \frac{\text{New Amount} - \text{Old Amount}}{\text{Old Amount}} \times 100
\]

In this case:
- Old Amount (last year's funds) = $950
- New Amount (this year's funds) = $1,045

Now we can substitute these values into the formula:

\[
\text{Percent Change} = \frac{1,045 - 950}{950} \times 100
\]

Calculating the difference:

\[
1,045 - 950 = 95
\]

Now substitute this back into the formula:

\[
\text{Percent Change} = \frac{95}{950} \times 100
\]

Calculating the division:

\[
\frac{95}{950} = 0.1
\]

Now multiply by 100 to get the percent change:

\[
0.1 \times 100 = 10\%
\]

So, the percent change in the amount the group raised is **10%**.
