savings table

[nickthrolson]

Let us say we wanted to create a savings table. The columns represent the interest rates (6,7,8,9,10) percent. The rows represent the years (1,2,3, ... up to 12) If the savings in any given cell where = (1+interest)^(number of years) where in this case ^ is the power then print the table

 

I need help with this can anyone give me example how to start this off? for class is I'm in for college reading the book cant find any similar examples. Thanks!

Is this what you want to create?

+----------+----------------+
|          | 6%             | ..
+----------+----------------+
| 1st year | base+intrest^1 | ..
+----------+----------------+
| 2nd year | base+intrest^2 | ..
+----------+----------------+
| 3th year | base+intrest^3 | ..
+----------+----------------+

 

Then this should do it:

<?php
$base = 100;
$years = range(1, 12);
$percents = range(6, 10);
$number_of_years = sizeof($years);
$total_percentages = sizeof($percents);
for ($i = 0; $i < $number_of_years; ++$i) {
    for ($j = 0; $j < $total_percentages; ++$j) {
        $base += ($base * ($percents[$j] / 100))^$years[$i];
        print 'Year: '. $years[$i] . ' Percentage: ' . $percents[$j] . ' Base+Intrest: ' . $base . '<br>';
    }
}
?>

 

It misses the markup to create the table though

This produces this output:

Year: 1 Percentage: 6 Base+Intrest: 107

...

Year: 12 Percentage: 10 Base+Intrest: 10120
