Answer:
$1,229.75
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 3.25% into a decimal:
3.25% ->
-> 0.0325
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:


Lastly, subtract A from P to get the interest earned:

The first one is the answer
Answer:
4 gallons
Step-by-step explanation:
80/5 will give you 16 so for each gallon the car can move 16 milles
so 64/16 = 4 so he will need 4 gallons of gas in order make the trip
