Question

Jason is ordering a flower arrangement. He can choose any combination of roses and carnations for his flower arrangement, and he does not want to spend more than $20. If roses cost $2 each and carnations costs $4 each, which inequality represents all possible combinations of x roses any y carnations. EXPLAIN HOW YOU GOT THE ANSWER.

Multiple choices:
F. 2x + 4y < 20
G. 2x + 4y ≤ 20
H. 4x + 2y > 20
I. 4x +2y ≤ 20

Answer 1

x = number of roses
y = number of carnations

the cost of roses is therefore: 2x
the cost of carnations is therefore: 4y

The sum of these needs to be less than or equal to 20.  Thus our solution:

2x + 4y ≤ 20

(G)
