Final answer:
Donna's father received $0.72 in change.
Step-by-step explanation:
To determine how much change Donna's father received, we need to subtract the total cost of his purchases from the amount he paid. The total cost of his purchases can be found by adding the cost of gasoline, juice, and granola bars. From the receipt, we can see that the gasoline cost $34.88, the juice cost $2.45, and the granola bars cost $1.95. Therefore, the total cost of his purchases is $34.88 + $2.45 + $1.95 = $39.28. Next, we subtract this total cost from the amount Donna's father paid: $40 - $39.28 = $0.72.
