Miles sells 3 raffle tickets for $18 and 4 tickets for $24. The pattern for the price of the tickets is the same. How much money

serg [7]

Answer:

If Miles sells 6 tickets the money he will collect be $36.

Step-by-step explanation:

Given:

Miles sells 3 raffle tickets for $18 and 4 tickets for $24.

The pattern for the price of the tickets is the same.

Now, to find the money miles will collect if he sells 6 tickets.

Let the money Miles will collect be $x.$

The ticket if sells will be 6.

As, Miles sells 3 tickets for $18.

And the pattern for the price is same.

So, 3 is equivalent to 18.

And, 6 is equivalent to $x.$

Now, to get the money by using cross multiplication method:

$\frac{3}{18} =\frac{6}{x}$

By cross multiplying we get"

$3x=108$

Dividing both sides by 3 we get:

$x=36.$

The money MIles will collect = $36.

Therefore, if Miles sells 6 tickets the money he will collect is $36.

What is the discontinuity and zero of the function

lukranit [14]

The discontinuity are the point wherein the function is not defined.
The zeros are the points wherein f(x)=0.
Computing the discontinuity points:
Set $x-1=0$ then the discontinuity point is at $x=1$ .
Comptine the zeroes:
Set $3x^2+x-4=0$
Compute the discriminant: $1^2-4(3)(-4)=49=7^2.$
Then with quadratic formula we get the solutions:
$(-1-7)/6=-8/6\\(-1+7)/6=1$
The two zeros are $\dfrac{-8}{6},1$
