Answer:
Your answers for #2 and #4 are incorrect.
Explanation:
For #2:
For one half hour in the garage, simply divide the one hour rate in half. 5/2= 2.5
For #4:
For 1.75 hours in the garage, the answer will be less than your answer for two hours. So, if 2hrs is $10, then the answer for 1.75 hrs must be 7.5
