Answer:
x = 302.
Step-by-step explanation:
If the brand new shampoo bottle originally contained 305 ounces and Nico lost 3 ounces, he will be left with 302 ounces of dog shampoo:
305 - 3 = 302
Considering he uses 1 ounce each time he bathes his dog, the number of baths he will be able to perform is calculated as follows:
x = 302 รท 1
x = 302
Nico will have bathed his dog 302 times before the bottle is completely empty.
