Answer:
We took $ 24 to the movies.
Step-by-step explanation:
Let total money be
On movies = Half of the money =
On popcorn = 
on candy = $2
On soda = $3
total money spent =

+ 2+3+1
x =

+ 2+3+1

150 = 12
150 +150 = 300 which = 24
150 + 150 + 150 = 450 which =36
the remaining 50 is 12 ÷ 3, so 4. 36 + 4 = 40.
therefore, 40 L of gasoline are needed to go 500km
Take the original price and times it by .8 (you could times it by .2 and then subtract from the original price but multiplying it by .8 is much easier) 64.9x.8= 51.92 take your discounted price and multiply it by 1.085 to account for the sales tax (you multiply by 1.085 to account for the price of the item and the tax you could times it by .085 and then add it on to the price of the item but this way it shortens the amount of steps needed) 51.92x1.085= 56.3332
Round to the nearest cent
Answer=$56.33
