Probably the third sorry if im wrong
She walked from her home to the park which is 1 and a half mile and 2 miles around the park and 1 and a half back home. Add them up and the answer is 5 miles.
Salt flows in at a rate of (5 g/L)*(3 L/min) = 15 g/min.
Salt flows out at a rate of (x/10 g/L)*(3 L/min) = 3x/10 g/min.
So the net flow rate of salt, given by in grams, is governed by the differential equation,
which is linear. Move the term to the right side, then multiply both sides by :
Integrate both sides, then solve for :
Since the tank starts with 5 g of salt at time , we have
The time it takes for the tank to hold 20 g of salt is such that
Answer: 15%
Because 3162.50 divided by 2750 is 1.15
1.15 x 100 is 115%
115-100 = 15% increase
Answer:
the money they need (1650$) minus the money they made (600$)
= 1050
1050 divided by 3 = 350
so they each need to make 350$
