Answer:
D. 4x+10≥135
Explanation:
We know that he has to deliver 10 packages on Friday.
so, 135-10=125
Now, we have Monday to Thursday, thats 4 days.
125/4=32
And, we know that it must be a minimum of 135 packages. So, using this information, we know that the answer has to be D.
Sorry if this was confusing, My mind works in ways that are hard to explain, with math. So, I hope this helps.
