If the price of theater tickets increases at 8% per year, about how long will it take to double the price?

Vladimir79 [104]

Answer:

$9\ years$

Step-by-step explanation:

Let

P----> the initial price of the ticket

y ---> the price of the ticket after t years

t---> the time in years

we know that

100%+8%=108%=108/100=1.08

$y=P(1.08)^{t}$ ----> equation A

If the price is doubled

then

$y=2P$ -----> equation B

equate equation A and equation B and solve for t

$2P=P(1.08)^{t}$

Simplify

$2=(1.08)^{t}$

Apply log both sides

$log(2)=t*log(1.08)$

$t=log(2)/log(1.08)=9\ years$

In a class test(3+) marks are given for every correct answer and (-2) marks are given for every incorrect answer (-2) marks are

Diano4ka-milaya [45]

The number of incorrect answers made by Radhika is 8; the number of incorrect answers made by Mohini = 13

<h3>How to solve algebra word problems?</h3>

We are given;

Marks obtained for 1 right answer = +3

Marks obtained for 1 wrong answer = −2

(i) Marks scored by Radhika = 20

Marks obtained for 12 correct answers = 12 × 3 = 36

Marks obtained for incorrect answers = Total score − Marks obtained for 12 correct answers = 20 − 36 = −16

Marks obtained for 1 wrong answer = −2

Thus, number of incorrect answers = (−16) ÷(−2) = 8

Therefore, the number of incorrect answers made by Radhika = 8

(ii) Marks scored by Mohini = −5

Marks obtained for 7 correct answers = 7 × 3 = 21

Marks obtained for incorrect answers = Total score − Marks obtained for 12 correct answers = − 5 − 21 = −26

Marks obtained for 1 wrong answer = −2

Thus, number of incorrect answers = (−26) ÷ (−2) = 13

So, the number of incorrect answers made by Mohini = 13
