Question 1: A store sells a jacket for $84 after a 30% discount. What was the original price?
- $110.00
- $112.00
- $120.00 (Correct answer)
- $114.80
Correct answer: $120.00
If the sale price is 70% of the original, then original = $84 ÷ 0.70 = $120.
Question 2: Which of the following sentences contains a misplaced modifier?
- She quietly closed the door behind her.
- Running through the park, the dog chased the squirrel. (Correct answer)
- Covered in mud, the car needed washing.
- Barking loudly, the dog scared the mailman.
Correct answer: Running through the park, the dog chased the squirrel.
'Running through the park' modifies 'the dog,' but the sentence implies the speaker was running, making it a misplaced modifier.
