Answer:
For every 1 hour he cleans 2/5 pools, so the ratio of pools to hours is 0.4:1
In 20 hours, Dave can clean 2/5 • 20 = 8 pools.
<em>20x</em>+20-4<em>-15x</em>=96-32
(next:subtract 96-32)
<em>20x</em>+20-4<em>-15x</em>=64
(next: then combine like terms)
<em>5x</em>+16=64
(next: subtract 16 from 64)
<em>5x</em>=48
(next: divide 48/5)
<em>x=9.6</em>
