A woman buys 50 eggs for $6.60. Some cost 12 cents each and the rest 14 cents each. How many eggs has she bought at 14 cents each?
- A. 20
- B. 20
- C. 20
- D. 20
Answer: Option C
Explanation:
Let, x eggs at 12 cents each and y eggs at 14 cents each.
1 dollar = 100 cents.
So, 12x + 14y = 660 and x + y = 50.
Solving these two, we get x = 20, y = 30.
