Hi there!
To solve this problem, we need to first find the amount of red tiles he used by subtracting 50 from 310, and then finding the sum of the two numbers.
310 - 50 = 260
Now, we know that there are 260 red tiles.
3 * 310 = 930
3 * 260 = 780
930 + 780 = 1710
So, the answer is 1710 tiles total.
Hope this helps!
