Help! I can't understand or find out the answer, I tried but I keep getting lost!

George rides a cab to work 3 days a week. He pays $3.50 for the cab to pick him up. He pays an additional fee for each mile driven. In one week, George paid $35.25. If he rides 11 miles each day, how much does he pay per mile?

Please help me! I can't find the right equation to find my answer. Please help!

3.50 * 3 = $10.50

3 * 11 = 33 miles

10.5 * 33x = 35.25

33x = 24.75

x = $0.75 per mile
