**Ravin**, Wednesday, October 24, 2012 at 8:01pmWell first you add up the currently known grades: 84, 65, and 76. (known grades)

Next multiply 80 by 4 to get the total amount for his test scores. (wanted average)

Finally subtract the total for his known grades from his wanted average.

**Ms. Sue**, Wednesday, October 24, 2012 at 8:02pm4 * 80 = 320

84 + 65 + 76 = 225

320 - 225 = 95
