Dale works mowing lawn and babysitting. He earns $8.60 an hour for mowing and $7.40 an hour babysitting. How much will he earn for 7 hours mowing and 1 hour babysitting

$67.60 sorry if I’m wrong. Don’t think I am though.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
