Answer:
The principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.
Step-by-step explanation:
Given
- Total accrued Amount A = 400.00 (Let say $)
- Interest rate r = 8% = 0.08
To determine
Principle P = ?
Using the formula
P = A / (1 + rt)
substituting A = 400.00, t = 9 and r = 0.08 in the formula
P = 400 / ( 1 + (0.08 × 9))
P = $232.56
Therefore, the principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.
Answer:
Step-by-step explanation:
Let the numbers be x and y.
<u>We have:</u>
<u>Sum the two and find x:</u>
<u>Find y:</u>
Distributive property -2x(2-5x) = -4x + 10x^2
Add -4x + 10x^2 - 3x^2
Simplified it is 7x^2 - 4x
Both should be yes..there is exactly one x input for every y input
