Prime numbers have 2 numbers: 1 and that number itself

Composite numbers have more than 2: example; 2 and 31: 2,3,5,7,11,13,19,23,29, and 31.

Calculate the amount of interest you'll have at the end of the indicated period.

Alexeev081 [22]

Answer:

$160

Step-by-step explanation:

I = 800 * 5 * 4% (I multiply the time and principal first, so I already have the wholes covered.)

I = 4,000 * 4% (now to convert 4% and 4000 into fractions.)

I = 4000/1 * 1/25 (Cross cancel if needed. GCF is 25.)

I = 160/1 * 1/1 (Just remove 1/1)

I = $160 (There's your answer!)

As a sales person Jonathan is paid 50 per week +3% of the total Amount he sells. This week he wants to earn at least 100. Write

steposvetlana [31]

Answer:

The Inequality with integer coefficient for the total sales is $5000+3x\geq 10000$

Hence Jonathan should make total sales of at least <u>1667</u> to earn at least 100.

Step-by-step explanation:

Given:

Amount paid per week = 50

Addition amount = 3% of Total sales.

Let the Total sales be 'x'.

∴ Additional amount = $\frac{3}{100}x$

Amount he wants to earn this week $\geq$ 100

We need to write the inequality with integer coefficient for the total sales and also to find the total sales.

Solution:

We cans say that;

Amount paid per week plus Additional amount should be greater than or equal to Amount he wants to earn this week.

framing in equation form we get;

$50+\frac{3}{100}x\geq 100$

Now we will make the denominator common using LCM we get;

$\frac{50\times100}{100}+\frac{3}{100}x\geq 100$

$\frac{5000}{100}+\frac{3}{100}x\geq 100$

$\frac{5000+3x}{100}\geq 100$

Multiplying both side by 100 we get;

$100 \times\frac{5000+3x}{100}\geq 100\times 100\\\\5000+3x\geq 10000$

Hence The Inequality with integer coefficient for the total sales is $5000+3x\geq 10000$

On solving the above equation we get;

Subtracting both side by 5000 we get;

$5000+3x-5000\geq 10000-5000\\\\3x\geq 5000$

Dividing both side by 3 we get;

$\frac{3x}{3}\geq \frac{5000}{3}\\\\x\geq 1666.67$

Hence Jonathan should make total sales of at least <u>1667</u> to earn at least 100.
