Ivan has a piggy bank that can hold 100 pennies and 50 dimes. How much, in dollars, does Ivan have if he has filled his two piggy banks with those coins?

Ivan has 50 x 10 = 500 cents from the 50 dimes in his one piggy bank. So, he has a total of 100 + 500 = 600 cents in one of his piggy banks. Since 100 cents is equal to 1 dollar, then Ivan has 600 / 100 = 6 dollars from one of his piggy banks. Therefore, Ivan has a total of $6 x 2 piggy banks = $12 from his two piggy banks.
Thus, the answer is 12.
