Sam has a jar contain 80 coins, all of which are either quarters or nickels. The total value of the coins is $14.60. How many of

DENIUS [597]

Answer:

She have 53 type of quarters and 27 type of nickels.

Step-by-step explanation:

Given:

Sam has a jar contain 80 coins, all of which are either quarters or nickels.

The total value of quarters and nickels is $14.60.

Now, to get each type of coin she have.

Let the number of quarters be $x.$

And let the number of nickels be $y.$

So, total number of coins:

$x+y=80$

$y=80-x\ \ \ ....(1)$

Now, the total value of coins:

$0.25(x)+0.05(y)=14.60$

Substituting the value of $y$ from equation (1):

$0.25(x)+0.05(80-x)=14.60$

$0.25x+4-0.05x=14.60$

$0.20x+4=14.60$

Subtracting both sides by 4 we get:

$0.20x=10.60$

Dividing both sides by 0.20 we get:

$x=53.$

The number of quarters = 53.

Now, to get the number of nickels by substituting the value of $x$ in equation (1):

$y=80-x\\\\y=80-53\\\\y=27.$

The number of nickels = 27.

Therefore, she have 53 type of quarters and 27 type of nickels.
