Question

A piggy bank contains Number of quarters as Nickels. If there are no other coins in the piggy bank and it is worth $2.10, how many quarters are there?

Answer 1

Answer: There are 7 quarters in all.

Step-by-step explanation:

Let the number of nickels be 'x'.

Let the number of quarters be 'x'.

1 nickel =$ 0.05

1 quarter = $0.25

So, According to question,

$0.05x+0.25x=2.10\\\\0.3x=2.10\\\\x=\dfrac{2.10}{0.3}\\\\x=7$

Number of nickels = Number of quarters = 7

Hence, there are 7 quarters in all.

Answer 2

7 Quarters
7*25=175
7*5=35
175+35=210
