Answer 1

Answer:

The equation represent the situation is:

First let x be number of small apartment

Since the total apartment is 18

Then number of large apartment is 18 – x

So the equation is:

17,600 = 800x + 1200(18-x)

Simplifying

17,600 = 800x + 21,600 – 1200x

400x = 4000

X = 10

Ninety percent of the ninth grade students at Richbartville High School take algebra. If 180 ninth grade students take algebra, how many ninth grade students do not take algebra? Please give answer and explain how to do it I'm so confused!

Answers

Let the total number of students be x.

Now, according to your question, 90% of x = 180

= 90/100 * x = 180

90x = 18000

Thus, x = 18000/90

= 200.

Thus, the total number of students are 200. Out of these, 180 are taking algebra. Thus, 20 students are not taking algebra.
