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

Serena and Sienna both work for a company that pays 12 dollars per hour for the first 40 hours of work in a week. If an employee
Free_Kalibri [48]

Answer:

87 total hours.

Step-by-step explanation:

The equation 456/12 Gives you how many hours Sienna worked. (38)

642-480 will give you how much money Serena made off of Just OT (162)

162/18 = 9 (9 is how many overtime hours Serena worked.)

Serena worked her normal 40 hours, then worked over time, so you have to add 40 to the equation.

9+40+38 = 87

Serena and Sienna worked 87 total hours.
