Answer:
4 hours
Step-by-step explanation:
We want to find at what x value, will y be the same for both companies. To do this, we can set the two expressions equal to each other.
25x+250=50x+150
To solve, we have to get all the variables to one side of the equation, and all the numbers to the other
Subtract 25x from both sides
250=25x+150
Subtract 150 from both sides
100=25x
Now, we have all the variables on one side, and the numbers on the other.
To isolate the variable, divide by 25
x=4
So, at 4 hours,the cost will be the same
Hope this helps! :)
Answer:

Or you could set it up as a proportion
12/1.25=48/x
Answer:
Step-by-step explanation:
Club A charges $30 membership fee and charges $7 for each movie.
You can write this as :
A = 30 + 7m (where m = number of movies)
Club B charges no membership fee and it costs $12 for each movie.
B = 12m
If we want to find how many movies a member must purchase for the total cost of the two clubs to be the same, this means we are trying to solve for "m" (number of movies) when A = B.
30 + 7m = 12m
Now you can just subtract 7m from both sides.
30 = 5m
Divide both sides by 5 to find "m'.
m = 30/5 = 6
Therefore a member must purchase 6 movies
