Answer:

Step-by-step explanation:

Given

21 ≤ - 3(x - 4) < 30 ← divide all 3 intervals by - 3

Remembering to reverse the direction of the signs as a result of dividing by a negative quantity

- 7 ≥ x - 4 > - 10 ← add 4 to each interval

- 3 ≥ x > - 6, that is

- 6 < x ≤ - 3 → A

Kayla is give a monthly allowance. She puts 40% of the money directly into her savings account. She spends $15 at the movies wit

£30
This is because if she has put 40% in to savings she has 60% left. This 60% is 15 + 3 (the money she spent at the movies and the money she has left) = £18
So 60% : £18
10% : £3 (divide by 6)
100% : £30 (multiply by 100)

Perry Mazza wants to borrow $30,000 from the bank. The interest rate is 6% and the term is for 5 years. What is the amount of in

omeli [17]

Answer: In both the case amount of interest is paid are:

1) $9000

2) $10146.76

Explanation:

Since we have given that

Principle amount = $30000

Interest rate = 6%

Number of years = 5 years

we'll use " Simple interest " first,

As we know the formula for " Simple Interest ":

$I=\frac{P\times R\times T}{100}\\\\I=\frac{30000\times 6\times 5}{100}\\\\I=$9000$

Now, we'll do it by "Compound Interest "

$Amount=P(1+\frac{r}{100})^n\\\\Amount=30000(1+\frac{6}{100})^5\\\\Amount=$40146.76$

So,

$Interest = Amount-Principle\\\\Interest =40146.76-30000\\\\Interest =\$10146.76$

Hence in both the case amount of interest is paid are:

1) $9000

2) $10146.76

Okay. I'll use a formula that my math teacher taught me.

3400(1-0.07)^15
3400(0.93)^15
