Harold, a marina manager, purchased two boats. He then sold the boats, the first
zaharov [31]

Harold paid $ 16,632 and $ 38,808 for each of the boats.

Since Harold, a marina manager, purchased two boats, and he then sold the boats, the first at a profit of 40% and the second at a profit of 60%, and the total profit on the sale of the two boats was 54 % and $ 88 704 was the total selling price of the two boat, to determine what did Harold originally pay for each of the two boats the following calculation must be performed:

  • 55 x 0.6 + 45 x 0.4 = 51
  • 65 x 0.6 + 35 x 0.4 = 53
  • 70 x 0.6 + 35 x 0.4 = 54

  • 88,704 x 0.7 = 62,092.80
  • 160 = 62,092.80
  • 100 = X
  • 100 x 62,092.80 / 160 = X
  • 38.808 = X

  • 88,704 x 0.3 = 26,611.20
  • 140 = 26,611.20
  • 100 = X
  • 100 x 26,611.20 / 160 = X
  • 16,632 = X

Therefore, Harold paid $ 16,632 and $ 38,808 for each of the boats.

spayn [35]

Answer:

The competition took 12.5 minutes.

Step-by-step explanation:

Let the time taken by Achilles to complete the competition is h hours.

Now, Achilles runs at a speed of 13 mph while the Turtle moves at a speed of 1 mph.

So, the competition was 13h miles long.

Now, Turtle will take h hours to complete h miles of the competition.

Now, given that (13h - h) = 2.5

⇒ 12h = 2.5

⇒ h = 0.208 hours.

⇒ h = 12.5 minutes.

Therefore, the competition took 12.5 minutes. (Answer)
