Answer:

<em>Option A. The water is draining at a constant rate of  </em>\frac{1}{2}<em> gallon per minute and the tank contained exactly 14 gallons when the drain was opened</em>

Step-by-step explanation:

<u>Graph Analysis</u>

We need to infer the situation presented in the graph. We first notice it's a line that relates the volume of water in a tank in gallons vs the time elapsed in minutes. The water is draining from the tank, it's evident since the line has a negative slope.

We can also notice the initial volume of water in the tank (at t=0) is 14 gallons. Two minutes later (at t=2 minutes) there are 13 gallons of water in the tank. Since the line will continue to decrease at the same rate, we can know the rate at which the water drains from the tank.

If there were 14 gallons of water and 2 minutes after, there were 13 gallons of water, then the gallon that left the tank took 2 minutes to do so, thus in one minute, the tank will lose half a gallon or \frac{1}{2} gallon per minute.

The only possible answer to exactly describe the situation is the option A

Aleksandr-060686 [28]

Answer:

  • 20-year fixed-rate at 7.5%
  • $106,219.32

Step-by-step explanation:

The shorter the term, the lower the amount of interest.

The lower the interest rate, the lower the amount of interest.

The loan that has both a shorter term and a lower interest rate will cost less in interest.

___

The total of payments for the 30-year loan is 396,232.87.

The total of payments for the 20-year loan is 290,013.55.

The amount saved by taking the shorter loan is the difference of these amounts: $106,219.32.

_____

You can use an amortization formula, spreadsheet, or a financial calculator to compute the payments for each loan. The total repayment amount is the product of the monthly payment and the number of them, 360 for the 30-year loan; 240 for the 20-year loan.
