ruby regexp find the pattern more than once

Question

value = "Men - $30, Women - $20"
# value = "Men - 0"
# value = "free"
data = /\$(\d*)/.match value

Currently:

data.to_a
 => ["$30", "30"]

I want:

data.to_a
 => ["$30", "30", "$20", "20]

How to accomplish that

If you don’t need repetitions, here you go: "Men - $30, Women - $20".scan(/\$(\d*)/). — Aleksei Matiushkin

Using String#scan

value = "Men - $30, Women - $20"

value.scan(/(\$(\d+))/)
# => [["$30", "30"], ["$20", "20"]]

value.scan(/(\$(\d+))/).flatten
# => ["$30", "30", "$20", "20"]
