Ahmad took a taxi to the bus depot. He paid the driver the fee of 134 and gave her an additional 18% tip.
(a) Let x be the amount Ahmad gave as a tip (in dollars). Using the values below, create a proportion that can be used to find x.
Values:
_________ _________
(b) Use the proportion from part (a) to find the amount Ahmad gave as a tip. Do not round any computations.
(c) What was the total amount Ahmad gave the driver, including the tip? Do not round any computations.
(a) The proportion can be set up as:
x/134 = 18/100
(b) Solving the proportion from part (a):
x/134 = 18/100
Cross-multiplying:
100x = 134 * 18
100x = 2412
Dividing both sides by 100:
x = 2412/100
x = 24.12
So, Ahmad gave a tip of $24.12.
(c) The total amount Ahmad gave the driver, including the tip, is the sum of the fee and the tip:
Total amount = 134 + 24.12 = $158.12
