You sell instruments at a Caribbean music festival. You earn $326 by selling 12 sets of maracas, 6 sets of claves, and $x$ djembe drums. Find the number of djembe drums you sold.

-Tom can wash cars for 9 hours 
-Tom can walk dogs for 12 hours 
-Tom can walk dogs for 4 hours then wash cars for 6 hours

All of these scenarios are under 15 hours and will make 72 dollars. If your teacher wants you to include both jobs then the last option will work the best but washing cars will get Tom the most money sooner. Have a nice day I hope this helps :)
