If p(x) is a function, then a real-world example might be
The amount of fish food, in grams required for the giant koi fish in the pond can be represented by the function
. If there are 50 fish, how many grams of fish food will you need?
Firstly, we need to know the price of the TV after the 110$ increase.
$165 x 1.10 = $181.50
[This is an increase of $16.50]
[1.10 is the equivalent of 110%. 1 being 100% and the .10 being 10%]
Now for the sales tax. We apply a similar method.
$181.50 x 0.065 = $11.79
6.5% of $181.50 is $11.79, so we add the two together to find the final cost.
The final cost of the TV is $193.29
