Answer:
equation ( 1.25x = 27.5 ) and x = 22.
Step-by-step explanation:
Shampoo bottle contains shampoo = ounces = 30.5 ounces
If 3 ounces spilled out the remaining amount of shampoo = ( 30.5 - 3 ) = 27.5 ounces.
Every time he shampoos his dog, amount of shampoo required = ounces = 1.25 ounce
If x is the number of times Nico can bathe his dog using the same bottle of shampoo then total amount used = (1.25) (x) ounces
Now remaining amount of shampoo = ttal amount used to shampoo the dog
(27.5) = (1.25x)
x= = 22 times
So answer will be equation ( 1.25x = 27.5 ) and x = 22.
