Answer:

Find cost difference between the two days

151 - 115 = 36

we can assume it costs 18$ a day


To find registration fee

five days = 18 x 5 = 90$

115 - 90 = 25

The registration fee is 25$

The formula is 18x + 25. Where x is the amount of days the dog is boarded

1. False

2. True

3. True
