You can set up an inequality with each of these. is/of = %/100
In this case you'd be solving for each of the "is".

(1) X/8.72=5/100
100X = 43.6
X= .436

(2) X/0.0436=5/100
100X=0.218
X= 0.00218

(3) X/0.436=5/100
100X=2.18
X=0.0218

(4) X/4.36=5/100
100X=21.8
X=0.218

I've heard of the method referred to as the Heart Method. Try looking up YouTube videos on how to solve these types of problems.

To solve 493x = 3432x+1, write each side of the equation in terms of base
sleet_krkn [62]

<u><em>Answer</em></u>

= 3.405 × 10⁻⁴

<u>Explanation</u>

If the question is correctly written, then it is very easy.

First, take the like terms on one side.

493x = 3432x+1

493x - 3432x = 1

-2939x = 1

Dividing both sides by -2939 to get the value of x.

x = 1/(-2939)

= - 0.0003405

= 3.405 × 10⁻⁴

Calculate annually compounded interest
Hunter-Best [27]

Answer:

$2,851.80

Step-by-step explanation:

Lets use the compound interest formula to solve:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

First, change 1.1% into a decimal:

1.1% -> \frac{1.1}{100} -> 0.011

Next, plug the values into the equation:

A=2,700(1+\frac{0.011}{1})^{1(5)}

A=2,851.80

She will have $2,851.80 after 5 years.
