Answer: It is 46.667 percent decrease

Step-by-step explanation:

To get the answer you subtract the two values first.

15-8=7

Then divide the answer by the original value. 7/15=0.46667

Then multiply the answer by 100

0.46667x100=46.667

And there you have it. Round as necessary.

Answer:

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = x² + 7 ( subtract 7 from both sides )

y - 7 = x² ( take the square root of both sides )

± $\sqrt{y-7}$ = x

Change y back into terms of x, thus

$f^{-1}$ (x) = ± $\sqrt{x-7}$

Finger [1]

Step-by-step explanation:

I assume "fair game" means that there is no profit and the expenses are equal to the income or sales.

we have clear expenses :

1× $100

3× $20

that is in total : $160

now we need to make sure that we generate exactly $160 by selling the tickets.

we have 100 tickets that should lead to $160.

how much should 1 ticket cost ?

well, 160/100 = $1.60
