Worked Solution
Step 1: Find the balance after the first top-up.
$3.50 + $20.00 = $23.50
Step 2: Subtract the fare for the trip to school.
$23.50 − $2.40 = $21.10
Step 3: Subtract the fare for the return trip home.
$21.10 − $2.40 = $18.70
Step 4: Add the second top-up from his mother.
$18.70 + $10.00 = $28.70
Ravi has $28.70 on his EZ-Link card.
Correct answer: $28.70
