Step-by-step explanation:
6x - A rose is $6 and you do not know how many she will buy so you would put an "x" after that symbolizing how many she will buy.
y - Carnations cost $1 and the amount purchased is unknown so you would use "y". Because they cost 1 dollar, you will not need to add 1 in front of "y" because "y" by itself is already known as one variable.
