PAULA BROUGHT $39.63 WORTH OF GROCERIES SHE GAVE TELLER TWO TWENTY DOLLARS BILLS WHAT IS THE FEWEST COIN SHE CAN GET IN CHANGE

MakcuM [25]

Answer:

4 coins

Step-by-step explanation:

First, let's find out how much she gave the teller:

2($20)=$40

Now, let's find out how much change the teller owes her:

$40.00-$39.63=$0.37 or 37 cents

The largest coin (under 37 cents), is a quarter which is worth 25 cents...

37-25=12 cents

The largest coin (under 12 cents), is a dime which is worth 10 cents...

12-10=2

The largest coin (under 2 cents), is a penny which is worth 1 cent...

2-1=1

And one more penny...

1-1=0

Therefore the fewest amount of coins she can get in change are a quarter, a dime, and two pennies, which is 4 coins.

How much money should be invested at 5% interest, compounded quarterly, so that 7 years later the investment will be worth $5000

vampirchik [111]

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\to &\$5000\\
P=\textit{original amount deposited}\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{quarterly, four times}
\end{array}\to &4\\
t=years\to &7
\end{cases}
\\\\\\
5000=P\left(1+\frac{0.05}{4}\right)^{4\cdot 7}\implies 5000=P(1.0125)^{28}\\\\\\ \cfrac{5000}{(1.0125)^{28}}=P$
