Both are C.
Step-by-step explanation:
16.8 gallons of water is equal to 67.2 quarts and 134.4 pints.
This is compound interest
r=rate
P=original amount
t=time in hours
is the number of glasses in n hours
price=cost time number of glasses
0.5 times
is
total glasses sold in n hours is
the function for money eraned in the nth hour is
Velocity Against Current = 108 / 3 = 36 km/hour
Velocity With Current = 108 / 2 = 54 km/hour
"vsw" means velocity in still water "cs" means current speed
vsw -cs = 36
vsw +cs = 54 Adding both equations
2 * vsw = 90
velocity in still water = 45 km/hour
current speed = 9 km/hour
