Jacqui has grades of 77 and 75 on her first two algebra tests. if she wants an average of at least 73​, what possible scores can she make on her third​ test?

Respuesta :

If she wants an average of 73 for 3 tests,
she needs  a total of 73 x 3 = 219

Scores needed for her 3rd test = 219 - 152 =  67.
