The answer is 535. Because 13 ten is one hundred and 3 tens and 4 hundred plus 1 hundred equal five hundred then you add the 3 tens and 5 ones together to 5 hundreds to get 535. Easy!
508 because 10 of the 10s make 100 and add it to the 400 and your left with 3 ones from the 10s and then you add it to the 5 ones so its 508
