$\bf \qquad \textit{Compound Interest Earned Amount}\\\\A=P\left(1+\frac{r}{n}\right)^{nt}\quad \begin{cases}A=\textit{accumulated amount}\to &8000\\P=\textit{original amount deposited}\\r=rate\to 5\%\to \frac{5}{100}\to &0.05\\n=\begin{array}{llll}\textit{times it compounds per year}\\\textit{is only once, so}\end{array}\to &1\\t=years\to &3\end{cases}$

$\bf 8000=P\left(1+\frac{0.05}{1}\right)^{1\cdot 3}\implies 8000=P(1.05)^3\implies \cfrac{8000}{1.05^3}=P\\\\\\6910.70\approx P\implies \stackrel{\textit{rounded up}}{6911 = P}\qquad therefore\qquad 6911~~\leqslant ~~P$

Rasheed bought two kinds of candy bars, chocolate and toffee, that came in packages of 2 bars each. He handed out 2/3 of the cho

mylen [45]

Answer:

Rasheed bought 9 packages of chocolates bar.

Step-by-step explanation:

Let C be the number of packages of chocolate bars.

Let T be the number of packages of toffee bars.

Rasheed handed out 2/3 of 2C of the chocolate bars and 3/5 of 2T of the toffee bars.

(1) Rasheed bought 1 fewer package of chocolate bars than toffee bars.

Equation becomes:

$C=T-1$ .....(1)

(2) Rasheed handed out the same number of each kind of candy bar .

Equation becomes:

$\frac{2}{3}\times 2C =\frac{3}{5}\times 2T$

=> $\frac{4C}{3} =\frac{6T}{5}$

=> $20C=18T$

=> $20C-18T=0$

Taking out 2 common, we get

$10C-9T=0$ ......(2)

Substituting $C=T-1$ in (2)

$10(T-1)-9T=0$

=> $10T-10-9T=0$

=> $T-10=0$

T = 10

As $C=T-1$

$C=10-1$

C = 9

Therefore, Rasheed bought 9 packages of chocolates bar.

Select any equations that have the same solution set as:

aliya0001 [1]

Answer: 6+4x=26, 4x=20

Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.

If you solve the equation, 2x+3=13 (subtract 3 from both sides)

2x=10 (divide both sides by 2)

x equals 5.

if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.
