conversations.value: I'm stuck on this math problem: Two white socks cost 25 cents more than a single brown sock. If two white socks cost 45 cents, how much would you pay for 15 brown socks?
  Can you help?

conversations.value: Two white socks cost 25 cents more than a single brown sock, meaning a brown sock is sold at $0.45-$0.25=$0.20
  The cost of buying 15 brown socks is 15*$0.20=$3
