.81x400=324

Need a total of 324 pts

Test grades so far 81,84,78,80 = 323

324-323=1

You need at least one more point to get an 81

Can someone please check my problem to see if it is correct if not please guide me thank you

**Ms. Sue**, Thursday, September 10, 2009 at 8:42pmIsn't your final grade figured on five tests?

0.81 * 500 = 405

405 - 323 = 82

**Kay**, Thursday, September 10, 2009 at 8:45pmok so instead of .81 x 400 it's 500? because it is 5 tests?
