Jill will go to the swimming pool on 20 different days this month.
a one day pass to the pool is $2.25.
a monthly pass to the pool is $30.00
how much money will jill save by buying a monthly pass?

15

Step-by-step explanation:

2.25 times 20=45

45-30=15

Step-by-step explanation:

To do this you have to figure each out in gallons per minute.

25/3 = 8 1/3.  This means that the gas is going into the truck at a rate of 8 1/3 gallons per minute.

40/5 = 8.  This means that the water is going into the tub at a rate of 8 gallons per minute.  

The gas is flowing into the truck faster.
