Answer:
12 x ≤ 48
Step-by-step explanation:
This inequality must have two sides, one that shows the expenditure Mary will do in function on the number of shirts (x) and other that shows the maximum money she can spend (48).
Her expenditure will depend on the shirts purchased (x) and as each shirt costs $12 the expenditure will be 12x. So, this expenditure MUST be equal or less to the maximum she can pay: $48.
The inequality will be:
12 x ≤ 48
This is the first of the options posted. From the others, none of them work.
Answer:
x<4
Step-by-step explanation:
To solve for x in the inequality equation, the terms should be rearranged such that x is on one side and integers are on the other side.
First, expand 4(x-3).
This will obtain:

Now, shift x terms and integers on each side.

After simplifying, it will get:

Finally, we can solve for x.
