The compound interest formula is:

Where:
A is the amount you will have.
P is the money you are investing.
r: is the interest rate (in decimals)
n: number of times the interest is compounded per year
t: time (in years)
The first thing is converting the rate from percentage to decimal:

Since the interest is compounded every month and a year has 12 months n=12.
Now we can replace the values in our formula:

We can simplify the exponents to get:

Finally, we can use our calculator to get 288463.33
After 18 your balance in your bank account will be $288463.33

Answer:
1.94%
Explanation:
The computation of portfolio return is shown below:-
Portfolio return = Sum of (return from stock × Weight of stock)
= (-1.38 × 35%) + (7.62 × 30%) + (0.40 × 35%)
= 0.483 + 2.286 + 0.14
= 1.94%
Therefore for computing the portfolio return we simply multiply the sum of return from stock with sum of weight of stock.
Answer:
x1 (1.5)+ x2(2.5) ≤ 80
(1)x1 + (1)x2 ≤ 40
Explanation:
Hi, we have to write a system of equations.
Since a basic model (x1) requires 1.5 hours for assembly, and a deluxe model requires 2.5 hours for assembly, the sum of both products must be equal or less than the assembler’s available hours per week (40).
Since we hired 2 assemblers, we have to multiply the hours available by 2.
x1 (1.5)+ x2(2.5) ≤ 40(2)
Simplifying:
x1 (1.5)+ x2(2.5) ≤ 80
Now, for the finishing is a similar process.
Since both models requires the same time for finishing (1), and there is only one finsisher.
(1)x1 + (1)x2 ≤ 40
