Answer:
[tex].75M+3<15[/tex]
[tex]M<16[/tex]
Step-by-step explanation:
This is a linear inequality so you would solve it as any normal linear system:
Subtract 3 from both sides to isolate the M term :
[tex].75M<12\\[/tex]
Divide each side by .75 to isolate M:
[tex]M<16[/tex]
That means you can watch less than 16 movies and stay under your 15GB limit.
If I helped, a brainliest would be greatly appreciated!
