Last year, there were 850 8th grades at Mike’s school. This year there are 1050. What is the percent change to the nearest whole number?

To find the percent change, we first need to calculate the difference between the two values:

1050 - 850 = 200

Next, we need to calculate the percent change. To do this, we will use the formula:

(percent change) = (change in value / original value) x 100

(percent change) = (200 / 850) x 100
(percent change) = 0.2353 x 100
(percent change) = 23.53%

Rounded to the nearest whole number, the percent change is approximately 24%.
