Linda has scored 84, 93, 91, and 60 on her previous four tests. What score does she need on her next test so that her average (mean) is 82?

Respuesta :

Answer:

She needs to score 82

Step-by-step explanation:

Mean of five test scores = 82

Let the score she got in fifth test = x

[tex]\frac{84+93+91+60+x}{5}=82\\\\\frac{328+x}{5}=82\\\\328+x=82*5\\\\328+x=410\\\\x=410-328\\\\x=82[/tex]
