Gabby has a bag containing 36 nickels and quarters. The total value of the coins is $5. How many quarters does gabby have?

There are 20 nickels and 16 quarters

Solution:

Let "n" be the number of nickels

Let "q" be the number of quarters

We know that,

1 nickel = 0.05 dollar

1 quarter = 0.25 dollar

Gabby has a bag containing 36 nickels and quarters

Therefore,

n + q = 36

n = 36 - q ------- eqn 1

The total value of the coins is $5

Thus we frame a equation as:

number of nickels x 1 nickel + number of quarters x 1 quarter = 5

0.05n + 0.25q = 5 ------- eqn 2

Substitute eqn 1 in eqn 2

0.05(36 - q) + 0.25q = 5

1.8 - 0.05q + 0.25q = 5

0.2q = 3.2

q = 16

Substitute q = 16 in eqn 1

n = 36 - 16

n = 20

Thus there are 20 nickels and 16 quarters

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
