The piney creek swim club is preparing for opening day. the pool holds 22,410 gallons of water and the water is being pumped in at 540 gallons per hour. The club has it's first practice in 42 hours. Will the pool be full in time?

Yes,

Step-by-step explanation:

all you do is 540x42 which gives you 22680 and the pool only needs to be filled up with 22410, so yes

You will pay $13.52 for this shirt.

Step-by-step explanation: 0.9435

Since the tax is 7.5%, you have to multiply 12.58 by 7.5% to find the amount of money paid as tax.

7.5% = 0.075

12.58 x 0.075 = 0.9435

Since we are dealing with money we have to round to the nearest hundredth -- 0.9435 = 0.94

Then to find the final cost of the shirt, we have to add 12.58 and 0.94 to get  $13.52.
