Question

A Sum of $14 is made of 92 coins consisting of dimes and quarters. How Many are there of each kind of coin

Answer 1

So first I would say, what if all of them were dimes, how far away would it be from $14?

So 92 coins * 10 cents = $9.20

So it's 4.80 dollars away from 14 dollars.

So if we were to switch one to a quarter, it would increase by 0.15 cents.

So we want to see how many increases we need to reach 4.80 dollars more.

4.80/0.15 = 32

So there are 32 quarters and 60 dimes.

Answer 2

Answer:

30 quarters and 60 dimes

hope this helps :)
