Answer:
She can buy a maximum number of 15 containers
Step-by-step explanation:
We are told from the question that:
Mrs. Phan needs at least 5 containers of tulips and at least 5 containers of lilies.
Tulips cost $6 per container and lilies cost $4 per container. If Mrs. Phan has a total of $75 to spend for the tulips and lilies, what is the greatest number of containers she can buy?
Let x represent the number of Can of tulips for both tulips and lilies
x ≥ 5 cans for both tulips and lilies
$6 × x + $4 × x = $75
6x + 4x = 75
10x = 75
x = 75/10
x = 7.5 cans
This means , 7.5 containers for tulips and 7.5 containers for lilies
Adding up both containers, we have :
7.5 + 7.5 = 15 containers
Therefore, the greatest number of containers she can buy is 15 containers
