Recall that:
Hence,
Answer:
1.) Incorrect,
2.) Correct
Step-by-step explanation:
1.) Let x be the amount of money,
After increasing x by 20%,

= 120 % of x
⇒ y = 1.20x
≈ 16.67%
Thus, x is approximately 16.67% less than y.
2.) First score = 60%,
Second score = x% ( let )
So, Average percentage score =
