OK, here, we can simply apply the values and solve for which one works.
23.50 * 3 = 70.50
23.25(3) + 17 = 86.75
Now, they are not equal.
Try another one!
27.50 * 5 = 137.50
23.25*5 + 17 = 133.25
Not correct either!!
Try another!
27.50 * 6 = 165
23.25 *6 + 17 = 156.50
NO! Lets try the second one!!
27.50*4 = 110
23.25 * 4 + 17 = 110
THIS ONE IS CORRECT!

Answer:
1. The distances are accurate.
2. 57 miles
Step-by-step explanation:
<u>Quiz 1 solution</u>
1 mile = 1.60934 km
10 miles will be;
10 × 1.60934 = 16.0934 km
Distance on the sign is 16 km.
The distance is accurate since 16.0934 km rounded up to nearest kilometre is equal to 16 km.
13 miles will be;
13 × 1.60934 = 20.92142 km
The distance on the sign is 21 km
This distance is accurate since 20.92142 km rounded up to nearest kilometre equals 21 km
55 miles will be;
55 × 1.60934 = 88.5137 km
The distance on the sign is 89 km
The distance is accurate since 88.5137 km rounded up to nearest kilometre is 89 km.
<u>Quiz 2 solution</u>
1 km = 0.621371 miles
92 km will be;
92 × 0.621371 = 57.166132 miles
Rounding up the answer to nearest mile gives 57 miles.
