Q2:The price of a pair of shoes increases from $68 to $81. What is the percent increase to the nearest percent?


The percent increase is ? %.

Answer 1

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

Explanation:

1) Decreased students = 23 -13 = 10

Decreased percentage =
`(10)/(23)*100`

`= (1000)/(23)\\\\= 43.47`

= 43%

2) Increased amount = 81 - 68 = $ 13

Increased percentage =
`(13)/(68)*100`

`= (1300)/(68)\\\\= 19.11`

= 19%
