The punch bowl at Felicias party is getting low, so she adds 12 cups of punch. The punch bowl now contains 11.5 cups of punch. How many cups of punch were in the punch bowl before Felicia refilled it

Initial cups = -0.5 cups of punch

Step-by-step explanation:

Added cups of punch = 12

Final cups of punch = 11.5

The initial cups of punch before it was refilled = final cups - added cups

Initial cups = 11.5 - 12

Initial cups = -0.5

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
