Answer:
$6.75
Explanation:
First, start with a minimum of $3 because she walked the golden retriever for one hour. then you would add half of that $3 so you would be adding $1.50
Then, get 75% of $3, which is $2.25 for the chocolate lab.
Last, add $2.25 to $3 and you get $5.25, then add that wonderful $1.50 and you get $6.75
I do hope this helps!
