Answer:
$12600
Step-by-step explanation:
If x represents the total investment, then the total interest is ...
(x/3)(0.02) +(x/3)(0.07) +(x/3)(0.08) = 714
x(.17) = 2142 . . . . multiply by 3; collect terms
x = 2142/0.17 = 12600
The total investment was $12,600.

Answer:
0.01097393689
Step-by-step explanation:
We can use the equation f(n) = 8*1/3^n-1 to find the nth term in this sequence. 8 being the first term, 1/3 being the common ratio
The equation is L = 34 – 0.5d for the water level, L, after d days
<h3><u>Solution:
</u></h3>
Given that , Suppose that the water level of a river is 34 feet
And that it is receding at a rate of 0.5 foot per day.
We have to write an equation for the water level, L, after d days
The equation can be framed for water level after d days which is found by calculating difference between initial level and receding level of water per day
Now , we know that,
<em>water level after d days = initial level – receded level of water.
</em>
L = 34 feet – number of days spent x rate of receding level per day.
L = 34 feet – d days x 0.5 foot
L = 34 – 0.5d
Hence, the equation is L = 34 – 0.5d
