Answer:

The jar contains 10 nickels and 10 dimes. Another answer is that the jar contains 4 nickels and 13 dimes.

Step-by-step explanation:

1 nickels = 5 cents

1 dime = 10 cents

<u>1st answer</u>

10 nickels = $0.50

10 dimes = $1.00

So 10 nickels + 10 dimes = $1.50

<u>2nd answer</u>

13 dimes = $1.30  

4 nickels = $0.20

So 13 dimes + 4 nickels = $1.50
