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:

Answer: ln ( 40) *100
Step-by-step explanation:
Substituting 140 in the equation,
140 = 100 + e^(.01q)
40 = e^(.01q)
Take the natural log of bot hsides
ln ( 40) = .01q
q= ln ( 40 ) * 100
