Answer: $4.50
Step-by-step explanation:
125=21.50+23x
This is the equation to find this situation since 125 was given and it equals the left over and the spent money.

103.5=23x
Very cool! Divide both sides by 23 to get 4.5=x
The bag of dog food would last for 21 days.
The bag contains 42 cups of dog food. If the dog eats 
cups everyday, the amount of cup in the bag decreases by cups everyday. This can be represented with this expression: 42 - d. Where d represents the number of days.
In order to determine the number of days in which the bag would be emptied, this equation can be used:
Number of days the dog food would last = number of cups in the cup / amount the dog eats each day
42 ÷
42 ÷ 
42 x 
= 21 days
