Gondor was able to repair a total of 3+5= <<3+5=8>>8 phones from Monday to Tuesday.

And the total amount he earned is $10x8= $<<10*8=80>>80.

He was able to repair a total of 2+4= <<2+4=6>>6 laptops from Wednesday to Thursday.

So, the total amount he earned is $20x6= $<<20*6=120>>120.

Therefore, the total amount he earned is $120+$80= $<<120+80=200>>200.
