Question 1113970: Berries are $3 per pound. Which inequality shows the number n of pounds you can buy if you have $20?
3n >= 20
3n <= 20
3+n<= 20
20-n<= 3
I think it’s b but not sure
Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! n stands for pounds
3n means n pounds at $3 per pound, or 3 x n
20 is the money you have. You cannot spend what you don't have, so you cannot spend more than 20.
-----------------------------------
3n >= 20 means 3 x pounds is more than 20. Can't be, you ONLY have $20.
------------------------------------
3n <= 20 yes, 3n equal or smaller than 20 makes sense. Especially that 20 is not divisible by 3, so with $20 you can buy 6 pounds, 6 x 3 = 18 and 18 < 20. This is your answer
------------------------------------------
The last two are there just to make you think :-)
