pool has 45000 gallons. It loses 780 gallons per hour, so the amount at any given time:

45000 - 780h, where h is the number of hours.

The chemical could be added once the amount of gallons in the pool hits 15000. So the equation to solve:

45000 - 780h = 15000

solve:

30000 = 780h

38.46 = h

It will take about 38.46 hours before chemical could be added. It will not take longer than 2 days because 2 days is 48 hours, and we only need about 38 hours.

kkurt [141]

Answer:

lets call the children, c, and call adult, a,

c+a= 52 eq 1: a=52-c

c=3a eq 2

take a's value from eq 1 and plug it into eq 2

c=3(52-c)

c=156-3c

4c=156

c=39 the number of children that attended the ball game.
