Answer:

#1) Well buying something 15 percent cheaper is like saying your buying something for 85% of its normal price.

Well a tax is adding onto somethign right? A percent means out of a hundred. A 5 percent tax is addding 5 percent to the hundred so really your paying 105 percent of the price. Convert into decimal you get 1.05

So assuming y is the original and the state Tax being 5% then

(y*0.85)1.05 (last option)

#2) Well we now x is adult tickets and y is child.

Adult tickets are $74

Youth is $35

Now we want to know c or total.

So 74x+35y=c (last option)

A music company sells CDs for a particular artist. The company has advertising cost of $4,000 and recoding costs of $10,000; The
alukav5142 [94]

Answer:

First, let's write all the costs:

$4,000 in advertising.

$10,000 in the recording.

$5,50 per cd.

Then we have that the cost will be:

C(x) = $4,000 + $10,000 + $5.50*x

where x is the number of CDs distributed.

C(x) = $5.50*x + $14,000.

Now, they win $7.20 per cd, so the tota wins are:

W(x) = $7.20*x

The profit will be the difference between the total win and the cost:

p(x) = $7,20*x - $5.50*x - $14,000 = $1.7*x - $14,000

Now with this function, we can calculate the number of CDs that the company needs to sell in order to break even, that is when the profit is exactly zero.

P(x) = $0 = $1.7*x - $14,000

$1.7*x = $14,000

x = $14,000/$1.7 = 8,235.3 CDs, that we should round up to 8,236.

This means that the company must sell more than 8,236 if they want to have a positive profit.

How do I solve this one
just olya [345]
6/7Y - 18/28 =-15/14
First, let's get a common denominator
24/28Y - 18/28 =-30/28
Move your terms to isolate Y
24/28Y=-12/28
Multiply by 28 on both sides
24/Y=-12
Times both sides by Y, then divide by -12
24/-12=Y
Simplify
-2=Y

I hope this Helps!
