Answer:
0 pints ≤ J ≤ 4 pints
Where J is the amount of juice that Carl bought.
Explanation:
Here we need to learn how to use the inequality symbols.
Let's define each one of them:
A < B (A is strictly smaller than B)
A > B (A is strictly greater than B)
A ≤ B (A is smaller than or equal to B)
A ≥ B (A is greater than or equal to B)
A ≠ B (A is different than B)
Ok, in this case, we know that Carl buys 4 one-pint cartons of milk.
Then the total amount of mil that he buys is 4 times one pint, this is:
4*1 pint = 4 pints
He has 4 pints of milk.
And we know that he buys less juice than milk, then if J represents the amount of juice that he bought, we need to have:
J < 4 pints
This means that the amount of juice that he bought is smaller than the quantity of milk that he bought (4 pints)
If we want to be more correct, we should write:
0 pints ≤ J ≤ 4 pints
Here we say that J needs to be a positive number (we can't buy a negative quantity of juice)
