Question

Milton Jones scored 88 and 93 on his first two tests in Buisness Management class.  What score must he get on his third test to keep at least an average of 84 or greater?

anonymous · Answer

$$\frac{83+93+x}{3}\geq 84$$ is a start

anonymous · Answer

or maybe just 
$$\frac{176+x}{3}\geq 84$$

anonymous · Answer

then multiply both sides by 3, and finally subtract $176$ so get $x$

anonymous · Answer

this is a lot of different types of questions. must be a strange class

anonymous · Answer

hmmm

anonymous · Answer

ok i think i made another typo, try 
$$\frac{88+94+x}{3}\geq 84$$
$$\frac{181+x}{3}\geq 84$$
$$181+x\geq 252$$
$$x\geq 71$$
