Answer:

Step-by-step explanation:

Lets calculate first for in state college

yearly tuition fees = $3,500

monthly living expense = $700

one year has 12 months so yearly living expense =$700 * 12 = $8,400

Yearly expense of the in state college = yearly tuition fees ($3,500 )+ yearly living expense($8,400)   = $3,500 + $8,400  = $11,900

____________________________________________________

Lets calculate first for  out of state college

yearly tuition fees = $6,000

monthly living expense = $400

one year has 12 months so yearly living expense =$400 * 12 = $4,800

Yearly expense of the out of state college = yearly tuition fees ($3,500 )+ yearly living expense($8,400)   = $6,000 + $4,800  = $10,800

Marshall invest $4500 into an account bearing 6% interest compounded semiannually. How much interest will be added into this acc
Sphinxa [80]

Answer:

$1547.62

Step-by-step explanation:

The principal Marshall invested is $4500.

The rate of interest is 6%

The compound interest formula is

A=P(1+r)^n

We substitute P=4500,r=0.06 and t=5 to obtain:

A=4500(1+ \frac{0.06}{2} )^ {2 \times 5}

We simplify to get:

A=4500(1+ 0.03)^ {10} = 4500 \times  {1.03}^{10}

This gives us:

A=6047.62

The interest after 5 years is

6047.62 - 4500 = 1547.62
