<human>:  Ben bought a lawnmower for his garden. He paid $100 for it. After six months, the value of the mower dropped by about 25%. Over the next year, the value of the mower dropped another 20% in value. How much is Ben's lawnmower worth after this time?
<bot>: How much did the lawnmower drop in value after 6 months? ** The first value drop of the lawnmower was 25/100 * 100 = $<<25/100*100=25>>25.
How much was the lawnmower worth after 6 months? ** So the lawnmower was worth 100 - 25 = $<<100-25=75>>75.
How much did the lawnmarder drop in value after 1 year? ** Over the next year, the value dropped another 20%, which is 20/100 * 75 = $<<20/100*75=15>>15.
How much is Ben's lawnmower worth after this time? ** So after all this time, Ben's lawnmower is worth 75 - 15 = $<<75-15=60>>60.
