Reuben has scores of 70,75,83, and 80 on four spanish quizzes. what score must he get on the next quiz to achieve an average of at least 80?

Sagot :

x - the score he must get

[tex]\frac{70+75+83+80+x}{5} \geq 80 \\ \frac{308+x}{5} \geq 80 \\ 308+x \geq 400 \\ x \geq 92[/tex]

He must get at least 92 points.
ok well If he gets a 92 percent he will have a 80!! :)
