nikitadnepr [17]

Answer:

5

Step-by-step explanation:

You save ⅓ of entry fee, so you save 1.20 and you pay 2.40. We only really care about the 1.20 reduction. 5 / 1.2 = 4.16 so he must go 5 times to get the 5 back

How much would $300 invested at 4% interest compounded monthly be
Anna11 [10]

Answer:

$412.92

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance </em>

<em>r = interest rate </em>

<em>n = number of times compounded annually </em>

<em>t = time </em>

<em />

The first step is to change 4% into its decimal form:

4% -> \frac{4}{100} -> 0.04

Now plug in the values:

A=300(1+\frac{0.04}{12})^{(12)8}

A=412.92

It would  be worth $412.92
