Jacqui has grades of 70 and 75 on her first two algebra tests. if she wants an average of at least 76, what possible scores can she make on her third test?
If you add 70 + 75 + 76 you get 221 take 221 and divide it by 3. yoy divide by three because you added together three numbers in the begining. 221 ÷ 3 is 73.6 so Jacqui can get a 73 or 74 to make the average she wants.
