21 - 3y = 36 - 6y

We're essentially just trying to get both of the "y's" with one another on the same side.

So, we must add 6y to both sides.

21 -3y + 6y = 36

Now, we must subtract 21 from both sides.

-3y + 6y = 36 - 21

Simplify.

3y = 15

Divide both sides by 3.

y = 15/3

y = 5

So, B) 5 is correct

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.
