Answer: To make 20 ounces of dye, we need 3 oz red tone, 6 oz of gray tone and 5 oz of brown tone.
To make 100 ounces of dye, we need 15 oz red tone, 30 oz of gray tone and 25 oz of brown tone.
Step-by-step explanation:
The amount of specific hair dye made by given ingredients=


Therefore , The amount of specific hair dye made by given ingredients=
qz
Multiply reciprocal of
to each ingredient to find the amount of each ingredient required to make 1 oz of specific hair dye.
To make 1 oz of specific dye, the amount of red tone needed
Similarly, Gray tone=
Brown tone=
Now, multiply 20, to each
To make 20 oz of specific dye, the amount of red tone needed
Similarly, Gray tone=
Brown tone=
To find each dye to make 100 ounces of dye, multiply 5 to the above amounts, [since
]
To make 20 oz of specific dye, the amount of red tone needed
Similarly, Gray tone=
Brown tone=
