Answer:
Step-by-step explanation:
Let d represent the number of dimes Molly has. Then she has 18-d nickels, and the total value (in cents) of her coins is ...
5(18 -d) +10d = 105
5d +90 = 105 . . . . . . simplify
5d = 15 . . . . . . . . . . . subtract 90
d = 3 . . . . . . . . divide by 5; number of dimes
18-d = 15 . . . . . number of nickels
Molly has 3 dimes and 15 nickels.
