Answer :
Let: P(f) = Profit from the flowers
f = number of flowers sold
1.4 = 140% markup of the flower
0.50 = cost to buy each flower
P(f) = 1.4(0.50f) - 0.50f
Solving for f:
500 = 1.4(0.50f) - 0.50f
f = 2500
Therefore, they should sell 2500 flowers to have a profit of $500.

Solving for f:

f = 2500
Therefore, they should sell 2500 flowers to have a profit of $500.
