Here we have

Brenda needed to make an average of 96 on her bowling scores, however, she makes an an error in her calculation as follows

She calculated are current bowling scores as

92 + 110 + 85 + 78 = 365 instead of

92 + 110 + 85 + 78 + 96 = 461

576 - 461 = 115

She needs to score 115 on her next game.
