Plz help me im stuck

Anna has a water bottle that is half full. After she drinks 15 fluid ounces from the bottle, it is only one-fifth full. What is the total capacity of the water bottle, in fluid ounces?

Answer 1

x = 50 ounces

Explanation:

call the capacity of bottle x ounce

Anna has a water bottle that is half full. -> x/2

After she drinks 15 fluid ounces from the bottle, it is only one-fifth full

-> (x/2)-15 = x/5

-> 3x/10 = 15

-> x = 50 ounces
