Question

Blossom's Flowers purchases roses for sale for Valentine's Day. The roses are purchased for $10 a dozen and are sold for $20 a dozen. Any roses not sold on Valentine's Day can be sold for $5 per dozen. The owner will purchase 1 of 3 amounts of roses for Valentine's Day: 100, 200, or 400 dozen roses. The payoff for buying and selling 400 dozen roses at the full price is:
$12,000
$6,000
$4,000
It cannot be determined.

Answer 1

The cost of the roses is $4000. Subtract that from cost of the dozens that are sold at $20 (full price).

You are given much extraneous information (information that is not needed) in the third and fourth sentences.

$8000 - $4000 = ?

You need to read the problem carefully.

I hope this helps.

Answer 2

$4000
