Answer:
Step-by-step explanation:
The formula for simple interest is prt = I, where p is the initial investment (our unknown in this case), r is the interest rate in decimal form, t is the time in years, and I is the interest earned. That is NOT the same as the amount of money in the account t years later.
For us,
p = ??,
r = .05,
t = 18, and
I = 225.
Filling in:
p(.05)(18) = 225 and
.9p = 225 so
p = 250
Answer:
The answer is $250.
Step-by-step explanation:
First, the money that his grandmother deposited is called the principal, P. Substitute the given values into the formula, interest equals principal times rate times time, and solve for P. Here, I is 225 dollars and t is 18 years.
Next, the percent given represents the interest rate, r, but first it must be changed to a decimal. To change it, move the decimal point 2 places to the left.
Now, multiply point 0, 5, and 18 to simplify the right side of the equation. The product is point nine.
Finally, divide both sides of the equation by .9 . The result is P equals $225 The principal, or original deposit, is $250.

Answer:
Depends on the wear. But ~ $5 to $20 USD
Step-by-step explanation:
The value of a 1914 German 50 Mark banknote can vary widely depending on its condition, rarity, and demand among collectors. In September 2021, a 1914 50 Mark German banknote in average to good circulated condition might be worth between $5 to $20 USD. However, if the banknote is in excellent condition with minimal wear and is considered rare due to specific features or historical significance, its value could be significantly higher.
