Answer:
After 6 months, the interest generated by the investment would be $21.10.
Step-by-step explanation:
To determine the interest that Preston McCord could earn by investing $ 1,400 in an account that pays 3.2% annual interest compounded monthly, leaving said money invested for a period of 6 months, it is necessary to perform the following calculation:
X = 1,400 x (1 + 0.032 / 6) ^ 0.5x6
X = 1,421.10
1421.10 - 1400 = 21.10
Thus, after 6 months, the interest generated by the account will be $ 21.10.
Answer:
x - y = - 1
Step-by-step explanation:
Given the 2 equations
5x + 4y = 13 → (1)
4x + 5y = 14 → (2)
Subtract (2) from (1) term by term , that is
(5x - 4x) + (4y - 5y) = 13 - 14
x - y = - 1
