Answer:
20 movies ; $70
Step-by-step explanation:
Company 1:
Monthly charge = $40 ; additional = 1.5 per movie
Let number of movies = x ; t = cost
Equation 1:
y = 40 + 1.5x
Company 2:
Monthly charge = $30
Additional = $2 per movie
Equation 2:
y = 30 + 2x
1) for equation 1 = equation 2
40 + 1.5x = 30 + 2x
40 - 30 = 2x - 1.5x
10 = 0.5x
x = 10/0.5
x = 20
Hence, 20 movies
B.)
y = 30 + 2x
y = 30 + 2(20)
y = 30 + 40
y = $70
