A bottle of salon shampoo costs $30 for 25 ounces. What is the unit price of the shampoo? choices: 0.83 ounces per dollar $0.83 per bottle 1.20 ounces per bottle $1.20 per ounce

Parth (parthkohli):

We have to find the value of 1 ounce. To do that, we would have to divide 30 over 25. \(\Large \color{MidnightBlue}{\Rightarrow {30 \over 25} = {120 \over 100} = $1.20 }\)
