Answer:
the artist cuts off 10 inches of ribbon in total
Step-by-step explanation:
2.5 × 4 = 10
 
        
             
        
        
        
Okay, so 75 counts for 30% (exams), 80 counts for 20% (term paper), and 85 counts for 50% (final exam)
So you would multiply 30% by 75, 20% by 80, and 50% by 85. That would be 22.5, 16, and 42.5. Add these numbers up, and put them over the total percentage, 100%. So you would have 81/100. The student's final average is 81%.
