The answer is C.
Answer A is wrong because there is only a total of 40 coins.
Next step work out 1/3 of the dimes.
So Answer B:
1/3 (dimes) = 4.3. That means there would have to be 13+ 4.3 =17.3 pennies. There isn't, so it's incorrect.
Answer D:
1/3 (dimes) = 5.6. So 17+ 5.6 = 22.6 pennies. Wrong.
Answer C:
1/3 dimes = 5. So there needs to be 15+ 5=20 pennies.
C and D are the only two answers where there are a total of 43 coins.
in C there are 1/3 more pennies than dimes.
