Question

Julie and Tim are both cable subscribers. Julie pays $70 per month plus an additional $4.25 for each movie she orders. Tim pays $49.50 per month plus an additional $5.50 for each movie he orders. Last month Julie ordered 12 movies. How many movies would Tim need to order for their monthly price to be the same?

Answer 1

Answer:

no of movies (m), by Tim = 13

Step-by-step explanation:

Julie payment = constant 70 + 4.25 per additional movie = 70 + 4.25 m

Tim payment = constant 49.5 + 5.5 per additional movie = 49.5 + 5.5 m

Julie order = 12 movies. So, final payment = 70 + 4.25 (12) = 70 + 51 = 121

Equalising Tim's equation, for finding Tim's movies for same final amount , 121 = 49.5 + 5.5 m  → 5.5m = 121 - 49.5 = 71.5 →  m = 71.5 / 5.5 = 13
