Answer:
$2.50
Step-by-step explanation:
The most you would be willing to pay to have a freshly washed car before going out on a date is $6
The smallest amount you would be willing to wash another person's car is $3.50
Therefore if you are going out and need to wash the car, the economic surplus that would be received from washing it can be calculated as follows
= $6 - $3.50
= $2.50
Hence the economic surplus that would be received from washing the car is $2.50
