You can spend at most $60 on beads. A bag containing red beads costs $2 per bag. A bag containing blue beads costs $3 per bag. Y

nexus9112 [7]

For this case, the first thing we must do is define variables.
We have then:
x: number of blue beads
y: number of red beads
We now write the inequations system:
$3x + 2y \leq 60

x\ \textgreater \ y$
Answer:
a system of linear inequations that represents the situation is:
$3x + 2y \leq 60 x\ \textgreater \ y$
