Answer:
10. needs work
11. correct
12. correct
13. correct
Step-by-step explanation:
In general, it is a good idea to write a statement that answers the question asked. Simply solving an inequality for "x" rarely answers the question (unless it is a question that asks for the value of "x"). It is often best to try to use the wording that the question uses.
It is also a good idea to say what your variable represents.
__
10.
The required relation is "cheaper than" so the "or equal to" case does not apply. The variable represents messages, so the solutions will be integers.
"Nadine can send and receive more than 33 messages so the unlimited plan is cheaper."
__
11.
"Becky can afford at most 8 fish."
__
12.
"Loretta must drive more than 260 miles farther to reach Pensacola."
__
13.
"Terri can spend at most 35 minutes listening to music."
_____
Additional comment
The wording of the question in problem 10 is unconventional, but we have elected to use it anyway in the above answer. We could write "The unlimited plan is cheaper if Nadine sends and receives a total of more than 33 messages."
