500 tickets were sold for a game for a total of $862.50. If adult tickets sold for $2.00 and children's tickets sold for $1.50,
Alexxandr [17]
You can work these in your head if you consider the revenue generated by the least contributor (children's tickets) and the difference in revenue between that and the larger contributor ($2.00 -1.50 = 0.50).

If all were children's tickets, the revenue would be 500*$1.50 = $750.00. The actual revenue exceeded that amount by $862.50 -750.00 = 112.50. This difference in revenue is made up by the sale of $112.50/$0.50 = 225 adult tickets. Then the number of children's tickets is 500 -225 = 275.

225 adult tickets were sold
275 children's tickets were sold.

_____
If you need an equation, you can write an equation using a variable for the number of adult tickets sold (the largest contributor).
.. (500 -a)*1.50 +a*2.00 = 862.50
.. 0.50a = (862.50 -750.00) . . . . . does this look familiar, yet?
.. a = 112.50/0.50 = 225

Rick has 12 action, 15 comedy, and 9 drama DVDS. find the ratio of action DVDS to the total of DVDS. Then explain its meaning ho
krek1111 [17]
Okay, to find the ratio, add up all the numbers of DVDs. 
You should end up with 36 DVDs.

The question states that you need to find the ratio between the action DVDs and the total amount of DVDs.

The amount of action DVDs is 12.

Now take 32 and 12, the ratio of the action DVDs and the total amount of DVDs to get your ratio.

The ratio is 12 out of 31, or 12:32
