Find the percent change. Round to the nearest percent.

215 1/2 lb to 133 1/4 lb

$315.99 to $499.89

To find the percent change, you need to follow these steps:

1. Determine the initial value (the starting quantity or amount).
2. Determine the final value (the ending quantity or amount).
3. Calculate the difference between the final value and the initial value.
4. Divide the difference by the initial value.
5. Multiply the result by 100 to get the percent change.

Let's start with the first example:

1. Initial value: 215 1/2 lb
2. Final value: 133 1/4 lb
3. Difference: 215 1/2 lb - 133 1/4 lb = 82 1/4 lb.
4. Divide the difference by the initial value: (82 1/4 lb) / (215 1/2 lb) ≈ 0.381.
5. Multiply the result by 100: 0.381 * 100 ≈ 38.1%.

Therefore, the percent change from 215 1/2 lb to 133 1/4 lb is approximately 38.1%.

Now, let's move on to the second example:

1. Initial value: $315.99
2. Final value: $499.89
3. Difference: $499.89 - $315.99 = $183.90
4. Divide the difference by the initial value: $183.90 / $315.99 ≈ 0.5819.
5. Multiply the result by 100: 0.5819 * 100 ≈ 58.19%.

Therefore, the percent change from $315.99 to $499.89 is approximately 58.19%.

(215.5-133.25)/215.5 = .38167 = 38%

Do the same process for the second problem.
