Question

UpStudy AI · Accepted Answer

To calculate Haley's percent decrease from Test 1 to Test 2, you can use the following formula for percent decrease:

$$
\text{Percent Decrease} = \left( \frac{\text{Old Score} - \text{New Score}}{\text{Old Score}} \right) \times 100\%
$$

Plugging in Haley's scores:

$$
\text{Percent Decrease} = \left( \frac{93\% - 86\%}{93\%} \right) \times 100\%
$$

$$
\text{Percent Decrease} = \left( \frac{7}{93} \right) \times 100\% \approx 7.5269\%
$$

Rounded to the nearest tenth:

$$
\text{Percent Decrease} \approx 7.5\%
$$

**Answer:** 7.5 %
Haley's percent decrease from Test 1 to Test 2 is 7.5%.
