Answer:
The answer is actually 74 days. I know how to algebraically solve this, however I am unsure how to transpose my work onto the computer.
Step-by-step explanation:
I can also tell you that edgenuity will say 74 is correct.
348 rounded to tens place = 350
348 rounded to hundreds place = 300 (possibly 400)
2 + 3x = 17
2 + 3(5) = 17
2+ 15 = 17
