conversations.value: I need a clearer understanding of how to solve: In a shop, there is a sale of clothes. Every shirt costs $5, every hat $4, and a pair of jeans $10. How much do you need to pay for three shirts, two pairs of jeans, and four hats?

conversations.value: Three shirts cost 3 * 5 = $15.
  Two pairs of jeans would cost 2 * 10 = $20.
  Four hats would in total cost 4 * 4 = $16.
  So for three shirts, two pairs of jeans, and four hats, you would need to pay 15 + 20 + 16 = $51.
