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.

Marco earns $36.50 per hour show that the relationship between the amount he earns and the number of hours he works is proportio

Korolek [52]

To establish this equation we first need to assign some variables.

Let us assign x as the number of hours he has worked

and assign y as the total amount of money that he has earned

Therefore the equation y=36.50x is the equation that correctly represents how much money he makes regardless of how many hours he works. Just plug in how many hours you want for x and then solve the equation and you will get how much money he makes in x amount of hours. This is also proportional because for every hour that he works he gets the same salary of 36.50. It is proportional because no matter how many hours he works the salary will go up the same amount for each extra hour he works. The proportion is 36.50 dollars per hour worked.
