To find the answer we can find the amount he will get paid separately.
The amount he will get paid on site A:
0.75 x 5
=$3.75
The amount he will get paid on site B:
0.25 x 5
= $1.25
To find the amount Joe get paid at site A than at site B, we can deduct the amount he get from site B by the amount he get from site A:

= $2.50
Therefore $2.50 is the answer.
Hope it helps!
