Sasha reads at a rate of 0.8 pages per minute in her favorite novel, but only 0.5 pages per minute in the autobiography she is currently reading. Her English class has a minimum reading requirement of at least 75 pages per week. This situation is represented by the inequality 0.8n+0.5a≥75, where n is the number of minutes she reads her novel and a is the number of minutes she reads the autobiography.

Which statement correctly explains a solution for this situation?

If Sasha reads the autobiography for 32 minutes, she can meet the minimum reading requirement by reading her novel for 62 minutes.

If Sasha reads her novel for 94 minutes, she meets the minimum reading requirement without reading any of the autobiography.

If Sasha reads the autobiography for 94 minutes, she meets the minimum reading requirement without reading any of her novel.

If Sasha reads her novel for 32 minutes, she can meet the minimum reading requirement by reading the autobiography for 62 minutes.
