Elian and Alberto won tickets at a arcade. When they put their tickets together they had exactly 100. Alberto won 10 tickets les

Black_prince [1.1K]

Answer: See explanation

Step-by-step explanation:

Number of tickets Elian won = e

Number of tickets Alberto won = A = e - 10

Therefore, Elian + Alberto ticket = 100

e + (e - 10) = 100

2e - 10 = 100

2e = 100 + 10

2e = 110.

e = 110/2

e = 55

Elina has 55 tickets

Alberto has 55-10 = 45 tickets

Steve went to Macy's to buy clothing, Steve got to the checkout, and he had

noname [10]

Answer:

$67.41

Step-by-step explanation:

We want to find out how much 30% off of $96.30 is. To do that, we need to first multiply $96.30 to find out how much 30% would be. Don't forget to change 30% into its decimal form (30% - > .3).

96.30 x .3 = 28.89

This means that Steve got $28.89 dollars removed from his final bill. To find the actual final bill, subtract 28.89 from 96.30.

96.30 - 28.89 = $67.41

If a company has total costs

Answer:

The break-even points are: x = 500, and x = 70

Step-by-step explanation:

The break even points are those x-values for which the Revenue equals the Cost, so there is no money lost.

Since the formulas for both Revenue and Cost are given, we find the breaking points by setting the functions equal to each other:

$C(x)=R(x)\\35,000 + 45\,x +0.2 \,x^2=\,615\,x-\,0.8\,x^2\\35,000 + 45\,x +0.2 \,x^2-\,615\,x+\,0.8\,x^2=0\\x^2-570\,x+35,000= 0$

where we have gathered all terms on one side of the equation and written the equation in standard form.

We can use the quadratic formula to solve for "x":

$ax^2+bx+c=0$ has solutions given by: $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

In our case, $a=1,\,\,b=-570,\,\,and\,\,c=35000$

So the solutions are:

$x=\frac{570+/-\sqrt{570^2-4*35000} }{2}\\x=\frac{570+/-\sqrt{184900} }{2}\\x=\frac{570+/-430 }{2}$

This leads to two solutions:

$x_1=\frac{570+430}{2} = 500\\x_2=\frac{570-430}{2} = 70\\$

These are the break-even points.
