Mr. Valenzuela’s new bottle of shampoo contains 60 ounces of shampoo. He uses 1/4 ounce of shampoo each time he washes his hair. Which equation can be used to find x, the number of washes after which 24 ounces will remain in the bottle?

Respuesta :

Well we know that the beginning amount of the shampoo is 60 , and the remaining is 24

so the equation would be :

0.25 x = 60 - 24

0.25 x = 36

x    =  36/0.25
x     = 144

hope this helps
