If f(x)= x^2 + 2x + 5, what is f(x + 3)?

Ok so first, you are trying to find, if cost of a sled is $99.50 the markup price is 95%, what is the selling price?

First you multiply $99.50 by 95% and get $94.525. Since you are finding the percent markup, you find add the $94.525, and get $194.025. Round it to $194.03.

$194.03

Hope this helps, have a good day. c;
