    Gayle has 36 coins, all nickels and dimes, worth $2.40. How many dimes does she have?

    Set up our given equations using n as the number of nickels and d as the number of dimes:
    1. n + d = 36
    2. 0.05n + 0.1d = 2.40
    Use our simultaneous equations calculator to get:
    n = 24
    d = 12
