Find the balance in the account. $2,500 principal earning 4%, compounded quarterly, after 4 years

Helen [10]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$2500\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &4 \end{cases} \\\\\\ A=2500\left(1+\frac{0.04}{4}\right)^{4\cdot 4}\implies A=2500(1.01)^{16}\implies A\approx 2931.4466123$

Two classmates, Annie and Whitney, plan to meet in the computer lab to type up their research papers. Annie can type at a speed

madam [21]

The page count will be 10 when the two students will reach the same count.

Step-by-step explanation:

Given,

Typing speed of Annie = 3 pages per hour

Pages already typed by Annie = 4

Let,

x be the number of hours.

y be the total pages typed.

y = 3x+4 Eqn 1

Typing speed of Whitney = 1 page per hour

Pages already types by Whitney = 8

y = 1x+8 Eqn 2

For same number of pages;

Eqn 1 = Eqn 2

$3x+4=1x+8\\3x-1x=8-4\\2x=4$

Dividing both sides by 2

$\frac{2x}{2}=\frac{4}{2}\\x=2$

Putting x=2 in Eqn 1

$y=3(2)+4\\y=6+4\\y=10$

Putting x=2 in Eqn 2

$y=2+8\\y=10$

The page count will be 10 when the two students will reach the same count.
