Ответ:
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
1st answer
10 nickels = $0.50
10 dimes = $1.00
So 10 nickels + 10 dimes = $1.50
2nd answer
13 dimes = $1.30
4 nickels = $0.20
So 13 dimes + 4 nickels = $1.50
