Jessica has 48 coins, some of them are nickels and some are dimes. How many of each does she have if she has $3.25 total? 69 POI
Mrrafil [7]

<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

n+d=48 --- (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:

0.05n + 0.3d = 3.25 --- (2)

From (1):

n=48-d

Substituting this value of n in (2) to get:

0.05(48-d) + 0.3d = 3.25

2.4-0.05d+0.3d=3.25

2.4+0.25d=3.25

0.25d=0.85

d=3.4

Finding n by substituting the value of d:

n=48-d

n=48-3.4

n=44.6
