At the end of each year, how much money would you earn in interest if you invested $200 and earned 5.5% simple interest?

Alborosie

$\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$200\\
r=rate\to 5\%\to \frac{5}{100}\to &0.055\\
t=years\to &1
\end{cases}
\\\\\\
I=200\cdot 0.055\cdot 1$

Alexis is going to Vegas for the weekend! She decides to try her hand at a new game that Casino QuickCash is promoting. For this

vfiekz [6]

Answer:

$10.46

Step-by-step explanation:

Amount that can be won by Alexis ( xi ) = $0, $8 , $12

probability ( pi )

P( $0 ) = 13 / 52 = 1 / 4

P( $8 ) = 15 / 39 ( given that she wins this when an even number is drawn from three remaining decks )

P ( $12 ) = 1 - 15/39 = 24 / 39

<u>a) Alexis expected winnings per game </u>

= ∑ xi * pi = ( 0 * 1/4 ) + ( 8 * 15/39 ) + ( 12 * 24 / 39 )

= $0 + ( 120 / 39 ) + ( 288 / 39 ) = $10.46
