The answer to that question is 5
P is the principal amount, $12000.00.
r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
t is the time involved, 3....month(s) time periods.
Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into "year" as well.
Do this by dividing your time, 3- month(s), by 12, since there's 12 months in 1 year.
So, t is 0.25....year time periods.
To find the simple interest, we multiply 12000 × 0.05 × 0.25 to get that:
The interest is: $150.00
Usually now, the interest is added onto the principal to figure some new amount after 3 month(s),
or 12000.00 + 150.00 = 12150.00. For example:
If you borrowed the $12000.00, you would now owe $12150.00
If you loaned someone $12000.00, you would now be due $12150.00
If owned something, like a $12000.00 bond, it would be worth $12150.00 now.
Answer:
S= $165 + $15*W
Step-by-step explanation:
The total amount Mario has saved at the end of any W week is called S.
$ 165 is the amount that Mario has already saved.And you know that at the end of each week he saves $ 15. So, for example, in week one Mario will have saved $ 15, in week two $ 30, in week three $ 45 and so on. This is expressed by the relationship $ 15*W. Taking into account that this amount saved is in addition to the $ 165 that Mario had already saved, the total amount that he has saved at the end of any week is:
<u><em>S= $165 + $15*W</em></u>
