$55 this is shown by doing 80/100=0.80. and 0.80*55=this is the answer
Answer:
4
Step-by-step explanation:
$6 is 20% of a $30 haircut
A=35+5t, b=100-8t, a=b when:
35+5t=100-8t subtract 35 from both sides
5t=65-8t add 8t to both sides
13t=65 divide both sides by 13
t=5 minutes
a=35+5(5)=60 gallons
So the tanks have an equal volume of 60 gallons after five minutes.
