Question

A florist bought 20 bunches of 10 rose flowers, each bunch for $ 120. He sold each flower for $ 10.00. Find his profit or loss​

Answer 1

Answer:

n - 2 = t (the number of tulips) n - 2 = d (the number of daisies) n - 2 = r ( the number of roses) The question is: are there only roses, daisies and tulips in the bouquet ? If yes we also have a fourth equation: r + d + t = n In this case we add the three equations above and we get 3n -6 = n (because n = r + d + t) 2n = 6 n = 3 If there are more than daisies, tulips and roses in the bouquet we have a system of three equations with four unknowns so the solution space is infinite.
