Answer:

$1307.69

Step-by-step explanation:

Let the original investment be x.

Note that a 30% increase in a value is equal to multiplying a value by 130% and a withdrawal is to take out money. The final amount is $1500. Let’s write the equation with the information we have.

Equation:

130%x - 200 = 1500

(130/100)x = 1700

x = 1700(100/130) = $1307.69

I hope this helps! :)

Answer:

$29,005.97

Step-by-step explanation:

Cn = Co * (1 + i)^n

Cn = 104,986.99(1+.05/1)^(1*5)

Cn = 104,986.99(1+.05)^5

Cn = 104,986.99(105)^5

Cn = 104,986.99(1.2763)

Cn = 133,992.96, total money at end

133,992.96-104,986.99= $29,005.97, interest accumulated
