Step-by-step explanation:

let the total charge be y

and the number of rose be x

Florist A charges

y=40+4.75x---------1

Florist B charges

y=25+5.2x--------2

to solve for the number of roses we need to equate 1 and 2

40+4.75x=25+5.2x

40-25=5.2x-4.75x

15=0.45x

x=15/0.45

x=33.33

The number of roses that will be less expensive to order from A is 33.33

Answer:

 

Step-by-step explanation:

33.33
