Question

450 students are graduating from Big Lake High School this year. 68 % of students plan to go to college. 14% plan to work. The rest don't know yet. How many students are not sure what they are going to do after high school?

Answer 1

81

Explanation:

The amount that have definite plans is `68%+14% = 82%`

So the amount that do not know is `100%-82% = 18%`

The total count of students is 450

So the count of do not know is 18% of 450
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`18/100xx450 = 81`

Answer 2

81 Students

Explanation:

Since 68 % + 14 % = 82 % students having plan of study and for work and 0nly 18 % [ 100-82=18] do not have any plan out of 100 student.

So if out of 100 students only 18 student do not having any future plan, so how many student out of 450 students do not having any future plan ?

`450*18/100=81`

Answer 81 Students
