Explanation

From the first sentence, calculate Randall’s change (20.00 – 19.44 = 0.56). Then it’s a matter of systematic tests to determine the various combinations of dimes and pennies that Randall could have received, stopping when one matches an answer choice listed:

5 dimes (0.50) + 6 pennies (0.06) = 11 coins Not an option in the choices
4 dimes (0.40) + 16 pennies (0.16) = 20 coins Not an option in the choices
3 dimes (0.30) + 26 pennies (0.26) = 29 coins Correct answer

Hence option C is correct!
