A bouquet With 3 roses, 3 tulips and 5 daisies cost 15.50; a bouquet with 5 roses, 5 tulips and 3 daisies costs 16.50. What would be the cost of a bouquet containing 6 roses, 6 tulips and 4 daisies

The answer is 3.

Explanation:

Let x be the total number of flowers. When the problem says that all but two of the flowers are of one kind, it means there are n−2 flowers of that kind. Therefore, x−2 of them are roses, x−2 of them are tulips and x−2 of them are daisies. Assuming that this exhausts the list of flowers, we can write x−2+x−2+x−2=x which gives n=3

    the box has volume x^2h.  the cylinder has volume x^2h/4.  v = πr^2h = x^2h/4  πr^2 = x^2/4  r^2 = x^2/(4π)  r = x/(2√π)  b
