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]

Answer:

Nickels = 44.6

Dimes = 3.4

Step-by-step explanation:

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 $d$ :

$n=48-d$

$n=48-3.4$

$n=44.6$
