Answer:
396
Step-by-step explanation:
it's it's 396 because if you add 99 more you will get 495.
each percentage is 99, so 99 x 5 is how many students there are 99 x 4 is the answer.
Sorry for my messy handwriting but this is the answer
Percent increase=increase/original times 100
increase=26-21=5
original=21
so
5/21 times 100=0.23809523809523809523809523809524 times 100=23.809523809523809523809523809524
round
24%
so 24% increase
