Step-by-step explanation:

Formula to find the price of an item after t years after withe a depreciation rate of r% is $A=P(1-\dfrac{r}{100})^t$ , where P = Initial value of item.

Given: P = $15,000, r= 30%

Then, the value of car after t years will be :

$A= 15000(1+\dfrac{30}{100})^t\\\\\Rightarrow\ A=15000(1+0.30)^t\\\\\Rightarrow\ A=15000(1.30)^t$

The required general formula for the value of the car t years after its purchase:

$A=15000(1.30)^t$

Artist 52 [7]

Answer:

6 weeks

Step-by-step explanation:

Easier way to solve: If she takes 7 quizzes each week, 7 times something (amount of weeks) equals 42.

7 X <u>6</u> = 42

Solving with algebra: We know that hanna takes six quizzes a week and takes a total of 42 quizzes, therefore the unknown (x) is the amount of weeks she takes the quizzes.

Amount of weeks X amount of tests per weeks = 42 quizzes

<em>x </em>X 7 = 42

42/7 = 6
