Krystal and 4 friends were going to the movies. each ticket cost $12. they bought 2 buckets of popcorn at $4.50 each and then each person bought their own soda at $4.75 each. how much money did they spend in total? a) $89.50 b) $92.75 c) $96.25 d) $99.50

They spent $92.75 in total (option B).

Step-by-step explanation:

Hi, to solve this problem we have to analyze th informaton given:

Number of people : 5 ( krystal and 4 friends )

cost of each ticket : $12

cost of each bucket of popcorn: $4.50

Number of buckets of popcorn : 2

cost of ach soda : $4.75

So, we have to multiply the cost of each ticket by the number of people ($12 x 5),  add the cost of each soda multiplied by the number of people ($4.75 x 5), and finaly add the cost of 2 buckets of popcorn (2 x $4.50).

Mathematically speaking:

$12 x 5 + $4.75 x 5 + $4.50 x 2 =

$60 + $23.75 + $9 = $92.75

In conclusion, they spent $92.75 in total (option B).

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
