c. Next month, Jay plans to order 7 movies.
d. This month, Jay's total bill is $ 78.50.
What will be his total bill for the month?
How many movies did he order this month?

Answer 1

y=f+3.5x

Explanation:

Let the total bill be y

and let the number of movies be x

let the flat fee be f

given that he pays $3.5 per movie

and his total bill is $54

The expression is given bellow for his total bill

y=f+3.5x

For 5 movies his total bill is $54

54=f+3.5(5)

54=f+17.5

54-17.5=f

f=36.5

Therefore the flat fee is $36.5
