Joey invest $900 at 4% simple interest for 2 years but he wants to know how much money he will have after only 18 months. Determ
malfutka [58]
Well, bearing in mind that, a year has 12 months, so 18 months is really just 18/12 of a year, or 3/2 a year, then

\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$900\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=years\to \frac{18}{12}\to &\frac{3}{2}
\end{cases}
\\\\\\
A=900\left( 1+0.04\cdot \frac{3}{2} \right)

Please help ASAP! Only answer if you know the correct answer! Thanks :)
ruslelena [56]

Answer:

29 Minutes

Step-by-step explanation:

The original speed is given in miles per hour (like a car), but the answer is asking for miles per minute, so we must convert the speed into miles per minute first. To do this, we set up this equation: \frac{10.1 miles\ }{1 hour}x\frac{1}{60minutes} which equals  \frac{0.168333333miles}{minute}. We can then divide the desired number of miles by the speed in miles per minute. Here is the eqaution for this \frac{4.9miles}{\frac{0.168333333miles}{1minute} }. The miles cancel and you are just left with 29.1 minutes after you divide 4.9 by 0.168333333. Hope this helps!
