You received a 85, 88, and a 94 on your last three math exams. What grade would you need on your next exam to have an average of 90? (Show all work on your scratch paper and make sure you set up an equation)

You would need to get a ??????
to have an average of 90%.

Answer: 93

suppose: the grade we need on the next exam is x (x > 0)

to have an average of 90, we have the equation:

[tex]\frac{85+88+94+x}{4}=90\\\\<=>267+x=360\\\\<=>x=360-267\\\\<=>x=93[/tex]

so the grade we need on the next exam is 93

Step-by-step explanation:

[tex]suppose: the grade we need on the next exam is x (x > 0)

to have an average of 90, we have the equation:

\begin{gathered}\frac{85+88+94+x}{4}=90\\\\ < = > 267+x=360\\\\ < = > x=360-267\\\\ < = > x=93\end{gathered}485+88+94+x=90<=>267+x=360<=>x=360−267<=>x=93

so the grade we need on the next exam
