Question

Katie gave Melanie $2.45 in dimes and nickels. If 10 coins were dimes, how many coins were nickels?

Answer 1

29 coins were nickels

Explanation:

first you figure out how many dollars 10 dimes equals. You would do 10 x 10= 100. Then you do $2.45-$1.00 to subtract the amount of dimes. You are left with $1.45. Then you make that 145/5 and get 29! So 29 coins were nickels.
