Answer:
swing voters are people who don't decide on a candidate at the start of a
presidential campaign.
The simplest form of an interest equation is A = P(1+rt)
where A = the total amount of money at the end, P = the principal (or amount of money you started with), r = the rate in percent, and t = the time in years.
In this case, P = 15000, r = 0.03 (because 3% in decimal form is 0.03), and t = 1:

So, after 1 year he will get $15450 back, making him $450 more.
A definition of a common ration Is the number multiplied must be the same for each term in the sequence. The common ratio is the amount between each number in a geometric sequence. To determine the common ration you can just divide each number from the number preceding it in the sequence. Here is an example I found of a common ration to further help you
2,4,8,16
16/8=2 you would then continue to divide to ensure that the pattern is the same for each number
8/4=2
4/2=2 the ratio is the same for each one so the common ration would be 2 I hope this helps could I please get a brainliest :)
