75 percent of the students in study hall finished their math hw before study hall was over. if they were 18 more students who finished their math hw than students who didn’t finished thier math hw, how many students are there on study hall? ? plzz i will give you 100 pointd

1314 students (Work? Ok)

Step-by-step explanation:

73x18=1314

Plzzz gimme points if correct

lets assume there are x students in study hall.

75 % has complete the math hw.

so number of students who completed math hw = x × 75/100 = 3x/4

now number of students who didnt complete the homework

= total number of students - total number of students who finished the homework

= x - 3x/4 = x /4

now as per 2nd statement

number of students completed math hw = number of students not completed math hw + 18

3x/4 = x/4 + 18

3x/4 - x/4 = 18

2x /4 = 18

x/2 = 18

x = 18×2 = 36

so total 36 students were there. i hope it helps.
