Question 77341
The price a flower shop charges for roses is inversely proportional to the number of days before Valentine's Day that the order is placed.
P = k/d
-------
A dozen roses ordered ten days before valentine's Day costs $12.00 while the same order placed five days before Valentine's Day costs $24.00. 
12 = k/10
k=120
Therefore, Formula: P=120/d
--------
What is the cost of a dozen roses ordered one day before Valentine's day?
p=120/1 = $120
