2 workers 8 dollars per hour and 40 hours
mutiply
2*8*40=640 dollars
now costlabor/revenue (try to get to percent which is parts out of 100 so x%=x/100)
640/2000
64/200
32/100=32%
answer is 32%

So, Option D is true .
First of all, let's find the water tank total amount
according to the exercice, there were 2 L (L =liters) of water at 6 am (6hours after midnight ).
Consider T as total amount of water
so we have
T=(6×2)+2=14 as we already know it's emptying 2 L per hour
y=14-2x , here is the equation !
Answer:
y= -4/3x - 9
