Nick bronson is paid $6 for each birdhouse he assembles. if he made 12 yesterday and 17 today, how much money he earn?

He made $72 yesterday, and $102 today. Total he made $174.
Hope this helps.

For 1 bird house he got $6. If he makes 12 bird houses he will make $72. Put 1 over 6 ( 1\6) and (12\?) Cross multiply and divide, that = $72.
If he makes 17 bird houses he will make $102. Put (1\6) and (17\?) Cross multiply and divide and that = $102 
$102+$72=$174
