Step-by-step explanation:
14/15 - 2/3 =
14/15 and 2/3 lcm is 15
so 14/15 becomes 14/15
 - 2/3 become 10/15
15÷5=3 and 10÷5=2
so 14/15
 -10/15=4/15
14-10 = 4
answer is 4/15 and since 15 can't be divided by 4 equally it is in simplest form at 4/15
 
        
             
        
        
        
The total would be $2.73.
