Answer:
$ 10.55
Explanation:
Given,
The amount he earned by walking dog = $ 12.50,
His spending = $ 6.95,
So, the remaining amount = earning - spending
= 12.50 - 6.95
= $ 5.55
After borrowing $ 5,
Final amount he has = 5.55 + 5 = $ 10.55,
If he spent all the amount to pay for snacks,
Then the amount paid for snack would be $ 10.55.
Hence, THIRD OPTION is correct.
