Answer:
3. 3 : 5; 3: 5
Step-by-step explanation:
First, let's find the leght of the sides of each octagon.

The area of an octagon is defined by

Replacing the area

Therefore, the side of the first octagon is 1.6 inches long.
Its perimeter is: 


Therefore, the side of the second octagon is 3.8 inches long.
Its perimeter is
.
Now, let's divide to find each ratio:
(the ratio between sides).
(the ratio between perimeters).
Therefore, the closest ratio is 3. 3 : 5; 3: 5
Well the all paid 10.35×3=31.05 with the tip. The tip is 35.05/100×15=4.6575. To know how much they paid without the tip you just 31.05-4.6575=26.39
