conversations.value: Jessie's community built a new hedge. Each section of the hedge used 30 pieces of concrete blocks that cost $2 per piece. The hedge has eight sections. How much did they spend on the concrete blocks?

conversations.value: They used 30 x 8 = 240 concrete blocks for the eight sections.
  So, they spent 240 x $2 = $480 on the concrete blocks.
