Answer:
5 movies were purchased during the month.
Step-by-step explanation:
You pay $40 each month for satellite TV, plus $3.50 for every movie you purchase.
Let there be x movies purchased in a month.
The bill amount is = $57.50
The equation forms:
\(40+3.50x=57.50\)
Solving for x;
\(3.50x=57.50-40\)
=> \(3.50x=17.5\)
So, x = 5
Hence, 5 movies were purchased during the month.
