Let's multiply each term for the other one.

I mean: x*x; x+7; -3*x; -3*7

So x²+7x-3x-21

We add up like terms.

Final answer: x²+4x-21

A company collected $7,800 by selling shoes. The company had $6,084 left after paying the tax. What was the percentage of tax?
dezoksy [38]

Answer:

22%

Step-by-step explanation:

The percentage of tax can be found by calculating the percent change.

new - old / old

6084 - 7800 / 7800

= -0.22 or -22%

This means the price decreased by 22%, meaning you paid 22% in taxes.

Please really need help anyone

Answer:

<em>A = $5183.36</em>

Step-by-step explanation:

<u>Compound Interest</u>

It occurs when the interest is reinvested rather than paying it out. Interest in the next period is then earned on the principal sum plus previously accumulated interest.

The formula is:

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

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Abdul deposited P=$4000 into an account with r=2.6% = 0.026 compounded quarterly. Since there are 4 quarters in a year, n=4. We are required to calculate the amount in the account after t=10 years.

Applying the formula:

{\displaystyle A=4000\left(1+{\frac {0.026}{4}}\right)^{4*10}}

{\displaystyle A=4000\left(1.0065\right)^{40}}

A = $5183.36
