Can someone please help me with this math problem please

Answer:
$0.06
Step-by-step explanation:
Lets find the total cost of the items
3 cakes at 5.95 each
3*5.95 = 17.85
1 gallon punch at 2.09
The total cost of the items
17.85 + 2.09 = 19.94
She paid with a 20.00
20.00 - 19.94 = .06
She will get .06 back
