Question

Craig wants to use an elevator to carry identical packages having the same weight. Each package weighs 4 pounds and Craig weighs 90 pounds. If the elevator can carry a maximum of 330 pounds at a time, which inequality shows the maximum number of packages, n, that Craig can carry with himself in the elevator if he is the only passenger?

Answer 1

n ≥ 60
n ≤ 60
n ≤ 236
n ≥ 236

Answer 2

Answer 3

Since Craig weighs 90 pounds we have to subtract 90 from the maximum capacity of the elevator: 330. That's 240 pounds. Then we decide 240 by 4 to find out how many packages he can carry so 240m divided by 4 is 60. This means that Craig can carry no more than 60 packages with him on the elevator so the answer is the second inequality.

Answer 4

Thank you so much Erin :) I will fan you. Do you think you can help me with some more?

Answer 5

Sure how many do you have

Answer 6

Uhm, maybe like 2-3 questions?

Answer 7

Sure

Answer 8

Which expression is equivalent to 2(m − 4) + 1?

2m − 7
2m − 3
2m + 9
2m + 10

Answer 9

It would be 2m - 7 Correct?

Answer 10

Yes

Answer 11

Ana read 15% of her 46-page book.
Hillary read 11% of her 72-page book.
Roger read 12% of his 68-page book.
Juan read 14% of his 69-page book.

Who can read the greatest number of pages in a day?

Answer 12

Ana
Hillary
Roger
Juan

Answer 13

And this is the last one.

The sum of three consecutive numbers is 57. What is the largest of these numbers?

18
19
20
21

Answer 14

Ok so 3 numbers added together equals 57. So 3n=57 divide by 3 on each side of the equation and you're left with n=19. In this case 19 is the middle number so the other two numbers are 18 and 20 because they are consecutive numbers

Answer 15

So what would it be?

Answer 16

Of 18, 19 and 20, 20 is the largest.

Answer 17

Alright, and what about the book question?

Answer 18

Sorry didn't see that one. ok so Ana read 15% of 46 so to find that we simply multiple .15 by 46 to get 6.9. So Ana read 6.9 pages. Just do that for the rest of the people and see who read the most

Answer 19

I did 11 multiplied by 72 and that gave me 792, I know that isn't correct

Answer 20

Hillary: 0.11 times 72 = 7.9

Answer 21

Ahhh, Alright I get it.

Answer 22

awesome

Answer 23

Juan read the most pages

Answer 24

Yup

Answer 25

Alright, that is it. Thank you so much!

Answer 26

Sure no problem ;)
