Answer :
Answer: The driver has $95.25 after the last ride.
Step-by-step explanation: First we need to know how much money he recieved from each ride. Multiply 3.5 with each number.
$3.5 x 10 = $35
$3.5 x 5.5 = $19.25
$3.5 x 19 = $91
Now add them up.
$35 + $19.25 + $91 = $145.25.
However, he spends $50 on gas. So subtract $145.25 and $91.
$145.25 - $91 = $95.25.
Therefore, the driver has $95.25 after the last ride.
