Question 776405: Hi, I setted up the equation, but when I solved it. It wouldn't work when I plugged it in to the story.
Question goes as..
One morning a certain number of passengers got on an elevator at the main floor of an office building. Four got off at the second floor, 2/5 of the reaminder at the third floor, 75% of the remainder at the fourth floor, and 3 on th fifth floor. If the elevator was empty at this point, how many got on the elevator at the main floor?
Here's my work, I know the answer is 24. But when I solved my equation I end up with 18.
Let X= Amount of people that go on from the main floor.
.75(2/5(x-4))-3= x
3/4(2/5x-8/5)-3= x
30x/20-120/20-3= x
30x/20-6/1-3/1
30x/20-9/1= x (Multiply both sides by 20)
30x-180=20x
10x=180
[x=18]
Did I do this correctly? I'm positive I didn't. The answer should be 24, but my teacher wants me to solve it with equations.
Again! I would really appreciate it if anyone could help me! Thanks!
