Answer:

$51.75

Step-by-step explanation:

Okay, so. They decreased there interest by .15. It is really nothing.  So, we have no clue how many years. So, we will just use one year. We would start by multiplying 50 and 3.5% that will equal 1.75. Then we would add it up. 50 + 1.75, it will equal to 51.75.

Therefore your answer is $51.75

Hope this helps!

A baseball team won 20 games and lost 10 games. What percent of the games did the team win?
wel

Answer:

66%

Step-by-step explanation:

- First, add 20 + 10 = 30. This will give you the total amount of games.

- Now, make this into a fraction for won games. This should be 20/30.

- Next, take 20/30 and simplify it. You should get 2/3 as a fraction.

- Now, take 2 and divide by 3. (2/3) You should get .66 repeating. This is equal to 66%.

- Therefore 66% is the answer.

- Hope this helps! If you need a further explanation please let me know.
