Question

caissa can download a maximum of 1000 megabytes (mb) of songs or movies to her smartphone each month. the file size of each movie is 85 mb, and the file size of each song is 4 mb. write an inequality that represents the number of movies (m) and songs (s) that caissa can download each month.

Explanation:

Step1: Define variables and their contributions

Let \( M \) be the number of movies and \( S \) be the number of songs. Each movie is 85 MB, so total movie size is \( 85M \) MB. Each song is 4 MB, so total song size is \( 4S \) MB.

Step2: Set up the inequality

The total size of movies and songs must be less than or equal to 1000 MB (the maximum she can download). So the inequality is \( 85M + 4S \leq 1000 \).

Answer:

\( 85M + 4S \leq 1000 \)
