Question: A plane flies between 4 cities; A, B, C and D. Passengers board and alight at each airport in every city when it departs and lands, respectively. The distance between city A and city B is 100 miles. The distance between city B and city C is 50 miles more than the distance between city A and city B. The distance between city C and city D is twice the distance between city B and city C. Calculate the total distance between city A and city D.
Answer: Since the distance between city A and B is 100 miles, and city B and C are 50 more miles apart than city A and B, then city B and C are 100 + 50 = 150 miles apart. The plane's total flying distance between cities A and C is 100 + 150 = 250 miles. The distance between city C and city D is twice the distance between city B and city C, meaning city C and city D are 2 * 150 = 300 miles apart. The plane flies a distance of 250 + 300 = 550 miles from city A to city D. The answer is 550.

They told him that on his 25th birthday, for every bill he still has, they will give him $1.5 in exchange. He spent 20% of his special bills. How much will he receive from his parents when he exchanges them?
A:
