Jasmine has an average of 95 on 15 quiz grades. If her teacher drops Jasmine’s lowest grade, a 72, which equation can beused to find n, Jasmine’s new quiz average?

A n = (95-72)/14
B n = [(95x15)-72]/14
C n = [(95x15)-72]/15
D n=[95(72-15)]/14

total of 15 tests = 95x15
take 72 away --> 95x15 - 72
find average of 14 tests ---> (95x15-72)/14
