Question

Hugh has to earn at least $400 to meet his fundraising goal. He has only 100 books that he plans to sell at $8 each. Which inequality shows the number of books, x, Hugh can sell to meet his goal?

20 ≤ x ≤ 400

40 ≤ x ≤ 100

50 ≤ x ≤ 400

50 ≤ x ≤ 100

Answer 1

please help ill give u medal

Answer 2

If each book is sold at $8, and you sell x books, how much will you get?

Answer 3

8x=?

Answer 4

Do you mean you'll get $(8x) ?

Answer 5

Yes

Answer 6

Then you're right.

Now, the money you earn has to be AT LEAST $400, and you'll earn $(8x) by selling x books.
Can you establish an inequality using the above information?

Answer 7

I dont know how to

Answer 8

@Callisto ??

Answer 10

No, you're not.

Answer 11

Symbol for "at least": \(\ge\)
Money you earn: 8x
at least: ≥
400: 400

Now, write an inequality for "monet you earn is at least $400"

Answer 12

8x≥400

Answer 13

Yes. Now, divide both sides by 8, what do you get?

Answer 14

X≥50

Answer 15

Yes.
Given in the question, we only have 100 books. So, the book you sell can't be greater than 100.
Can you write the whole inequality now?

Answer 16

So D?
