The percent increase is ? %.

Answer 1

Answer:

Step-by-step explanation:

23 x .565 = 12.995

12.995 rounded is 13.

So if the answer is .565, and you need to round to the nearest percent, it would be 57%.

Answer 2

Answer:

Step-by-step explanation:

1) Decreased students = 23 -13 = 10

Decreased percentage = $\frac{10}{23}*100$

                                       $= \frac{1000}{23}\\\\= 43.47$

                                       = 43%

2) Increased amount = 81 - 68 = $ 13

Increased percentage = $\frac{13}{68}*100$

                                     $= \frac{1300}{68}\\\\= 19.11$

                                    = 19%
