Answer: 28 nickels and 13 quarters

Step-by-step explanation:

Let the number of nickels represented by x and the number of quarters represented by y.

Then according to the question, we have the following equations :

x+y=41....................(1)\\\\0.05x+0.25y=4.65.................(2)

Divide 0.05 on both sides  of equation (2), we get

x+5y=93........................(3)

Subtract equation (1) from equation (3) , we get

4y=52\\\\\Rightarrow\ y=13

From (1), x=28

Therefore, there are 28 nickels and 13 quarters.

Which sentence uses present tense?
mamaluj [8]
As for this problem, the answer would most probably be and most likely be C. The piles of bones foreshadow Fortunato's fate.

In the first option, symbolizing wasn't used in present tense but a simple mixing of present and past tense. The more appropriate form of the sentence would be "The catacombs was dark and cold which symbolized death." This would be a lot more understandable and it will not create confusion to the readers because of the inconsistency of the usage of tenses. The second option and the last option would be both in past tenses. The correct one is used in plural present form.
