In order for Tom to earn a B in his math class, his test scores must average at least 80. On the first 5 tests, he has an average of 77. There is one test remaining, what is the minimum Tom needs to earn a B?

He will need to end with at least  80 x 6  =  480  points

His average is now 77:  77 x 5  =  385  points

So, he will need:  480 - 385  =  95  points      [Good luck!]
