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 <u>$36</u>.

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.

<em>So, 3 is equivalent to 18.</em>

<em>And, 6 is equivalent to </em>x.<em />

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

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

<em>By cross multiplying we get"</em>

<em />3x=108<em />

<em>Dividing both sides by 3 we get:</em>

x=36.

<u><em>The money MIles will collect = $36.</em></u>

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

Use the discriminant of the following quadratic equation to state the number and type of solutions. 3x^(2)+4x-5=3x+2
krek1111 [17]
3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions
