Question

Nico dropped the brand new bottle of dog shampoo and 3 ounce spilled out. He measured 1 1/4 ounces each time he shampoos his dog and the bottle of shampoo originally contained 30 1/2 ounces. What is an equation and value of x the number of times Nico can bathe his dog using this one bottle

Answer 1

30 1/2 - 3 = 27 1/2

27 1/2 = 1 1/4x

he can bathe his dog 22 times

Explanation:

Answer 2

equation ( 1.25x = 27.5 ) and x = 22.

Explanation:

Shampoo bottle contains shampoo =
`30(1)/(2)` 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 =
`1(1)/(4)` 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=
`(27.5)/(1.25)` = 22 times

So answer will be equation ( 1.25x = 27.5 ) and x = 22.
