Question

Last six weeks Joseph made an 88 average in class. This six weeks he made a 92. What is the percent of change?

Answer 1

The percent of change in Joseph's average grade from 88 to 92 is calculated as approximately 4.55% using the formula ((New Value - Old Value) / Old Value) x 100%.

Step-by-step explanation:

To calculate the percent of change from Joseph's average grade of last six weeks to this six weeks, we can use the formula:

Percent of Change = ((New Value - Old Value) / Old Value) × 100%

Last six weeks, Joseph made an average of 88. This six weeks, he made a 92. Applying the formula, we get:

((92 - 88) / 88) × 100% = (4 / 88) × 100%

Calculating the above expression gives us:

(4 / 88) × 100% ≈ 0.04545 × 100% ≈ 4.545%

So, the percent increase in Joseph's average grade from the last six weeks to this six weeks is approximately 4.55%.
