How much more interest is owed on $900 for 9 months then for 6 months? 6 months = 2.4% rate 9 months = 2.9% rate
stiv31 [10]
Keeping in mind that 6 months is not even a year, since there are 12 months in a year, then 6 months is really 6/12 years, and 9 months is 9/12 years, then


\bf ~~~~~~ \textit{Simple Interest Earned on 9 months}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$900\\
r=rate\to 2.9\%\to \frac{2.9}{100}\to &0.029\\
t=years\to \frac{9}{12}\to &\frac{3}{4}
\end{cases}
\\\\\\
I=900(0.029)\left( \frac{3}{4} \right)\\\\
-------------------------------

\bf ~~~~~~ \textit{Simple Interest Earned on 6 months}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$900\\
r=rate\to 2.4\%\to \frac{2.4}{100}\to &0.024\\
t=years\to \frac{6}{12}\to &\frac{1}{2}
\end{cases}
\\\\\\
I=900(0.024)\left( \frac{1}{2}\right)

check their difference, that much.

Rick took his family out for dinner. He planned to leave a 15% gratuity on the bill. What is the total cost of the bill is 123.5
Mazyrski [523]

Answer:

142.03 would be your answer

Step-by-step explanation:

You can multiply 123.50 by 15, which gets you $1852.50. Divide that by 100 and you are left with $18.525, which you can round to $18.53. Add that to what the cost of the bill was and you are left with $142.03
