<u>Answer:</u>
Nickels = 44.6
Dimes = 3.4
<u>Step-by-step explanation:</u>
We know that Jessica has 48 coins of which some are nickels and some are dimes so we can write it as:
n = amount of nickels
d = amount of dimes
--- (1)
We are to find the number of nickels and dimes if their total worth is $3.25.
Since a dime is worth 10¢ and a nickel is 5¢, so it should be:
--- (2)
From (1):
![n=48-d](https://tex.z-dn.net/?f=n%3D48-d)
Substituting this value of
in (2) to get:
![0.05(48-d) + 0.3d = 3.25](https://tex.z-dn.net/?f=0.05%2848-d%29%20%2B%200.3d%20%3D%203.25)
![2.4-0.05d+0.3d=3.25](https://tex.z-dn.net/?f=2.4-0.05d%2B0.3d%3D3.25)
![2.4+0.25d=3.25](https://tex.z-dn.net/?f=2.4%2B0.25d%3D3.25)
![0.25d=0.85](https://tex.z-dn.net/?f=0.25d%3D0.85)
![d=3.4](https://tex.z-dn.net/?f=d%3D3.4)
Finding
by substituting the value of
:
![n=48-d](https://tex.z-dn.net/?f=n%3D48-d)
![n=48-3.4](https://tex.z-dn.net/?f=n%3D48-3.4)
![n=44.6](https://tex.z-dn.net/?f=n%3D44.6)
