Asked by Jade

Fred would like to get at least a C in the class. He got a 68 on the first test. Write an inequality and then solve to find out what Fred would need to get on his next test to have a C in the class.

• C≥68
(I honestly do not know how to even start this out.)

What grade represents a C? Let's say it's a 75. Then just consider the total points he needs to have a 75 average:

68 + p >= 2*75

If a C is some other number, then just make the adjustment and solve for p, the number of points he needs.
