Question

What is the percent decrease when the balance in a bank account goes from $300 to $60?
The percent decrease is 20%.
The percent decrease is 25%.
The percent decrease is 80%.
The percent decrease is 87%.

Answer 1

To find the percent decrease from $300 to $60, you can use the formula:

\[
\text{Percent Decrease} = \left( \frac{\text{Original Value} - \text{New Value}}{\text{Original Value}} \right) \times 100
\]

In this case, the original value is $300 and the new value is $60.

1. Calculate the decrease:
\[
300 - 60 = 240
\]

2. Now plug the values into the formula:
\[
\text{Percent Decrease} = \left( \frac{240}{300} \right) \times 100
\]

3. Simplifying the fraction:
\[
\frac{240}{300} = 0.8
\]

4. Now multiply by 100 to get the percentage:
\[
0.8 \times 100 = 80
\]

So the percent decrease is **80%**.
