When the movie is half over, popcorn sells for half price. Full price popcorn is $3.50, and drinks are $1.35. Determine the cost
Nady [450]
Full price of popcorn: $3.50 
Price of popcorn after half the movie: $1.75
price of drinks: $1.35 

The question is....."Determine the cost for purchasing 3 orders of popcorn and 3 drinks when the movie is half over." 

$1.75*3=$5.25
$1.35*3=$4.05

the price of the 3 orders of popcorn would be $5.25 
The price of the 3 orders of drink would be $4.05 

5.25 + 4.05 = $9.30 

In total the 3 orders of popcorn and 3 orders of drink would cost $9.30

Hope this helps! :)

Ok so what you're trying to do is get L by itself so to do this you move everything to the other side:
A=L*WH
\frac{A}{WH}=L
So you answer would be: C
