Think:

7:55 a.m. is 5 minutes (5/60 hrs) before 8 a.m.;

from 8 to noon it's 4 hours, and from noon to 2:40 p.m. is 2 2/3 hours.

Thus, you're in school 5/60 hrs + 4 hrs + 2 2/3 hrs, or

6 2/3 hrs + 5/60 hrs, or 6 40/60 hrs + 5/60 hrs, or

6 45/60 hrs, or 6 3/4 hrs.

Of course there are other ways in which you could do this problem:

4 hrs 5 min plus 2 hrs 40 min comes out to 6 hrs 45 min, or 6 3/4 hrs.

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.
