Some of the most common (and most dangerous) examples of simple interest are short-term payday loans, which some lenders also cal is not to be confused with a cash advance on a credit card.) Let's say that you're going to get paid in ten days, and you need some cash payday lender might lend you \( \$ 720 \) now, and you'll be asked to pay them back when your paycheck comes. Of course, you'll have to pa fee charged by these types of lenders is \( \$ 25 \) per every \( \$ 200 \) borrowed. How much would you have to pay back in ten days? The amount of money you'd have to pay back is \( \$ \)

22. \( 5-10 x \leq 45 \) OR \( x+4<-1 \)

(a) If interest is compounded monthly, how many times would the growth factor be applied in 2 years? The growth factor will need to be applied 24 times in 2 years. Part: \( \mathbf{1} / \mathbf{3} \) Part 2 of 3 (b) If interest is compounded monthly, how many times would the growth factor be applied in 6 years? The growth factor will need to be applied \( \square \) times in 6 years.

15. 1: Notice and Wonder: Two Sets of Equations What do you notice? What do you wonder? \[ \begin{array}{ll}\text { Set 1: } \\ \qquad f(x)=x^{2}+4 x \\ g(x)=x(x+4) & p(x)=-x^{2}+6 x-5 \\ h(x)=(x+2)^{2}-4 & q(x)=(5-x)(x-1)\end{array} \] \[ r(x)=-1(x-3)^{2}+4 \]

Calculate the derivative for \( f(x)=(\sqrt{x}+52)(\sqrt{x}-51) \) (Use symbolic notation and fractions where needed.) \( f^{\prime}(x)=\square \) help (fractions)
