Eric has scores of 73, 82, and 82 on his history tests. use an inequality to find the scores he can make on his final exam to receive a b in the class. the final exam counts as three tests, and a b is received if the final course average is greater than or equal to 80.

Hey there!

Let's find the minimum score for his fourth test, since it can be greater than or equal to that amount.

If the final course average has to be greater then or equal to 80, the sum of the four scores with be greater than or equal to 320 because 80 x 4 = 320.

The sum of the scores of the tests he has already taken is:

73 + 82 + 82 = 237

Subtract 237 from 320 to get the minimum score:

320 - 237 = 83

This means the minimum score he has to get for a B grade is 83.

The inequality to represent that is x ≥ 83.

Hope this helps!
