Answer:(15k-60)/2
Step-by-step explanation:
Can you please elaborate? I need to know if there are any flat fees and what the price of A is.
Here is an example though: florist C charges $3.00 a rose and a fee of $8.00 for delivery. Florist D charges $2.00 a rose and a delivery fee of $5.00.
If florist D marks up their price to $4.00 a rose, then when would it be cheaper to buy from florist C?
It would be cheaper to buy from florist C if you buy 4 or more roses.
The cost would be the same if you bought 3 roses.
Remember, this is just an example. Glad to help though! :)
