Answer 3

ummm is said i made an error for some reason it said it was wrong

What is the total number of days for this trip? Remember, Arelius will spend two days traveling to Rome and two days traveling back from Rome.

Answer 5

here is the whole question

Answer 6

Arelius lives in a small town outside of Rome. He wants to see the Senate forum in Rome. The journey from his home to Rome is two days long and will cost 4 denari. Arelius calculates that with 2 denari per day, he will be able to pay for food and lodging.

The function below can be used to determine c(d), the cost of the trip to Rome, where d represents the total number of days for the trip (including the days traveling to and from Rome).

c(d)= 8 + 2d

If Arelius wants to spend five days at the Senate forum, how many denari will he need for the trip?

Answer 7

...well then, you would have to plug in 9 instead of 5.

Answer 8

5 days to stay, 2 days to travel there, and 2 days to travel back.

Answer 9

So c(9) = 8+2*9. 8+2*9 = 26, so D

Answer 10

Answer 13

oh ok

Answer 14

Actually, the answer should be 4 denari traveling to Rome, 2x5=10 denari for each day spent in the Senate, and another 4 denari traveling back from Rome. That should be.... 18 denari? Huh. Wait a second. ...shouldn't.... shouldn't 18 be right....? Huh. This is a strange question. The equation they gave doesn't really match with logic..... huh.

Answer 15

That'w weird. They included the number of denari for the days traveling back and forth, but they still calculate it with the... 2 denari.... ohh I see. He still needs 2 denari for the days that he travels. I see.

Answer 16
