Answer:

2
\leq x
\leq 6

Explanation:

action figure cost = $3 <- constant

trading card cost = $6(# of trading cards) = 6x

to get poster: spend at least 15, no more than 39

15
\leq 3+6x
\leq 39

split into two equations

3+6x
\leq 39

3+6x
\geq 15

solve for x for each

3+6x
\leq 39

6x
\leq 36

x
\leq 6

3+6x
\geq 15

6x
\geq 12

x
\geq 2 or 2
\leq x

combine equations back together

2
\leq x
\leq 6
