If florist b increases the cost per rose to $5.20, for what number of roses is it less expensive to order from florist A? From f
nordsb [41]

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! :)

How can u find the slope of a equation
Tomtit [17]

Answer:

It is the rate of change (how far it goes up or how far it goes down)

Step-by-step explanation:

The slope of a line is a measure of how fast it is changing. This can be for a straight line -- where the slope tells you exactly how far up (positive slope) or down (negative slope) a line goes while it goes how far across. Slope can also be used for a line tangent to a curve. Or, it can be for a curved line when doing Calculus, where slope is also known as the "derivative" of a function. Either way, think of slope simply as the "rate of change" of a graph

Example: if you have a slope of 2 your equation would be y=2x+1

You would always do rise over run. rise over run means when you put your slope in a fraction the numerator would always go up or down and the denominator would be run and run means you would go left or right. it all depends on if it is positive or negative.

Hope this helps good luck @(^_^)@
