You pay $40 each month for satellite tv, plus $3.50 for every movie you purchase. write and solve an equation to find the number of movies purchased during a month with a total bill of $57.50.

40+3.50x5=57.50 so you purchased 5 movies for the total of 57.50 at the end of the month

40+3.5m=57.5 m=5 Because since they already spent 40 out of 57.5 dollars, the rest is used towards movies which is 17.5 dollars left and since each movies is 3.5 dollars you divide that which is 5 so they watched 5 movies. ;)
