$4(k+5)=2(9k-4)\qquad|\text{use distributive property}\\\\(4)(k)+(4)(5)=(2)(9k)+(2)(-4)\\\\4k+20=18k-8\qquad|\text{subtract 20 from both sides}\\\\4k=18k-28\qquad|\text{subtract 18k from both sides}\\\\-14k=-28\qquad|\text{divide both sides by -14}\\\\\boxed{k=2}\to\boxed{d.}$

400 passengers go on a coach trip.

Afina-wow [57]

Answer: ₹759407.56

Step-by-step explanation: Total No. of passengers = 400

1 Coach = 50 passengers

∴Total No. of coaches= 400/50=8 coaches.

Cost for each passenger= £23

∴Total cost for 400 passengers= 400x£23

= £9200 ( 1£=82.5443 ₹) ∴ Total cost for passengers = ₹759407.56

Money spent per mile= 70p

∴Money spent for 200 miles= 200x70p=14000p

(1₹=100p) thus, 14000p=₹140

Total profit= Money from the passengers- Money spent for fuel

∴₹759407.56- ₹140= ₹7,59,407.56

Actually I am a 9th grader and I have tried this question, so I am not sure for my answer, But I have tried my level best.

How much more would $1000 earn in 5 years in an account compounded continuously than an account compounded quarterly if the inte

choli [55]

$\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\\

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

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

A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}

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

compare both amounts.
