4x + 5y = 2(x + 3y)

4x + 5y = 2x + 6y   <em>distributed 2 on the right side</em>

2x + 5y = 6y           <em>subtracted 2x from both sides</em>

2x = y                      <em>subtracted 5y from both sides</em>

         if y = 2x

then 17(y) = 17(2x)

          17y = 34x

Answer: 34x

Given Information:

Years = t = 35

Semi-annual deposits = P = $2,000

Compounding semi-annually  = n = 2

Interest rate = i = 6.5%  

Required Information

Accumulated amount  = A = ?

Answer:

Accumulated amount  = $515,827

Step-by-step explanation:

The future value of amount earned over period of 35 years and interest rate 6.5% with semi-annual deposits is given by

FV = PMT * ((1 + i/n)^nt - 1)/(i/n))

Where  

n = 2

i = 0.065

t = 35

FV = 2000*((1 + 0.065/2)^2*35 - 1)/(0.065/2))

FV = 2,000*(257.91)

FV ≈ $515,827

Therefore, Anthony will have an amount of $515,827 when he retires in 35 years.
