Caissa can download a maximum of 1000MB of songs or movies to her smartphone each month. The file size of each movie is 85MB, and the file size of each song is 4MB. Write an inequality that represents the number of movies (M) and songs (S) that Caissa can download each month.
Q. Caissa can download a maximum of 1000MB of songs or movies to her smartphone each month. The file size of each movie is 85MB, and the file size of each song is 4MB. Write an inequality that represents the number of movies (M) and songs (S) that Caissa can download each month.
Identify variables and file sizes: Identify the variables and their corresponding file sizes.Movies are represented by M and each movie is 85MB. Songs are represented by S and each song is 4MB. Caissa can download a maximum of 1000MB each month.
Write inequality for total file size: Write an inequality that represents the total file size of movies and songs downloaded.The total file size for movies downloaded is 85M and for songs is 4S. The sum of these must be less than or equal to1000MB.So, the inequality is 85M+4S≤1000.
Check if inequality makes sense: Check the inequality to ensure it makes sense in the context of the problem.If M is 0 (no movies downloaded), then S can be at most 250 (since 4×250=1000). If S is 0 (no songs downloaded), then M can be at most 11 (since 85×11=935, and 00, which is greater than 01). The inequality seems to correctly represent the situation.
