The diagram on the right shows Aisyah who is looking at a lamp post. Given that the angle of elevation at the tip of the lamp post from Aisyah's eyes is 55° and the distance between Aisyah's eyes and the tip of the lamp post is 145 metres, calculate the horizontal distance d in metres. State the answer correct to three significant figures.

Option A: He currently has $470 with 3 weeks to go (taking the class 1 week later as planned). Saving $125 each week for 3 weeks would give him a total of $845, giving him the needed money to take the classes.

Option B: He currently has $470 with 2 weeks to go. Instead of just saving up an amount of $125 per week for the remaining 2 weeks, he decides to add $15, saving up to $140 per week instead. Saving this amount for 2 weeks gives him $280, bringing his total to $750, which is enough for him to take the classes.
So, therefore, the answer is C.
