Just dividing the volumes of the pan, 189 and one bar, 3, suggests that at most she'll be able to cut 63 bars.

But you'll also have to prove that you can divide it in a regular pattern. And you can:

9 divides by 1

10.5 divides by 1.5

2 divides by 2.

So no incomplete bars!

$\bf ~~~~~~ \textit{Compounding Continuously Interest Earned Amount}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$1000\\
r=rate\to 3.7\%\to \frac{3.7}{100}\to &0.037\\

A=1000e^{0.037\cdot 5}\implies A=1000e^{0.185}\\\\

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}

A=1000\left(1+\frac{0.037}{4}\right)^{4\cdot 5}\implies A=1000(1.00925)^{20}$

compare both amounts.

Greg plans to purchase a bicycle. Bike A costs $270 and has an expected maintenance cost of $36 per year. Bike B costs $360 and

monitta

Answer:

<h2> Bike A costs $270 and has an expected maintenance cost of $36 per year.</h2><h2 /><h3>"Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years."</h3>

Step-by-step explanation:

270-36x

there are 5 years so x=5

270 + 36(5) = 270 + 180 = <u>450</u>

If it were 6 years than x = 6

270 + 36(6) = 270 + 216 = <u>486</u>

Bike B:

360 + 20x

For option b x = 5

360 + 20(5) = 360 + 100 = 460

for option b it would be 6 years than x = 6

360 + 20(6) = 360 + 120 = <u>480</u>

<h3>Hope i helped!</h3>
