<human>:  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?
<bot>: How many concrete blocks did they use? ** They used 30 x 8 = <<30*8=240>>240 concrete blocks for the eight sections.
How much did they spend on the concrete blocks? ** So, they spent 240 x $2 = $<<240*2=480>>480 on the concrete blocks.
#### 480
