Ineed along with explanation of your work in order to be marked as brainliest! this is asap and due by ! last year, the number of students in oscar's class was 20% less than the number of students in haoxi's class. this year, the enrollment in oscar's class dropped by 25% and the enrollment in haoxi's class dropped by 10%. oscar now has 6 fewer students than haoxi. how many students were in haoxi's class last year?

Let x be the number of students in Oscar's class last year

Let y be the number of students in Haoxi's class last year

Last year, the number of students in Oscar's class was 20% less than the number of students in Haoxi's class.

x = y - 0.20* y

So x = 0.80 y > Equation 1

This year, the enrollment in Oscar's class dropped by 25% and the enrollment in Haoxi's class dropped by 10%. Oscar now has 6 fewer students than Haoxi

x is dropped by 25% so its 0.75x

y is dropped by 10% so its 0.90y

0.75x = 0.90y - 6

0.75x - 0.90y = -6 > Equation 2

Plug in x value in the second equation and find out y

0.75 (0.80y) - 0.90y = -6

0.6 y - 0.9 y = -6

-0.3 y = -6

y = 20

the number of students in Haoxi's class last year = 20 students

i got 142 as my answer
