X + 9 = 2x - 3
<u>-x -x </u>
9 = x - 3
<u> +3 +3</u>
12 = x
6+7+8+9+10=40 ********************
Answer:
Step-by-step explanation:
Let's assume
number of seats in each row =x
we are given
The number of seats in each row exceeds the number of rows by 20
number of seats = number of rows +20
x = number of rows +20
so, number of rows =x-20
total number of seats = (number of seats in each row)*(number of rows)
so, we can plug values
and we get
now, we can solve for x
since, number of seats can not be negative
so, number of seats in each row is 63.....................Answer
The future value of the investment if the interest is compounded monthly is $89,354.89.
<h3>What is the future value of the investment?</h3>
Given that;
- Principal P = $20,000
- Annual interest rate r = 5% = 5/100 = 0.05
- Time t = 30 years
- Compound monthly = 12
- Future value = A = ?
Using the compound interest formula;
A = P( 1 + r/n )^(nt)
We plug in our values.
A = 20000( 1 + 0.05/12 )^(12 × 30)
A = 20000( 1 + 0.0041666666666667)^(360)
A = 20000( 1.0041666666666667)^(360)
A = 20000( 4.46774965 )
A = 89354.89
Therefore, the future value of the investment if the interest is compounded monthly is $89,354.89.
