Mia spent 6 hours studying for an exam, and she received an A on the exam. Normally, she would have spent that time watching TV instead of studying. Mia figures she could have made a B after studying only 3 hours, but she really wanted an A. What is Mia ’s marginal cost in terms of TV viewing to move from a B to an A on the exam?

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
