Question

Please help and show step by step

Answer 1

75 students

Explanation:

(70% Students)

(100 Students Left)

----

x = number of students left

`(70-x)/(100-x)` = .6

------

multiply by (100-x)

70 - x = .6 (100 - x)

70 - x = 60 - .6x

70 - 60 = x - .6x

10 = .4x

x = 10/.4

x = 25

Then, you subtract 25 from 100.

100-25 = 75 students

1. Find 70% of 100. 100 x 0.70 = 70.
2. Find 60% of 70. 70 x 0.60 = 42.
3. The answer is 42. Hope that helps!
