Answer :
Sure! Let's break down the problem step-by-step.
The hair stylist uses the following ratios for the hair dye:
- Red tone: [tex]\(1 \frac{1}{8}\)[/tex] oz
- Gray tone: [tex]\(\frac{3}{4}\)[/tex] oz
- Brown tone: [tex]\(\frac{5}{8}\)[/tex] oz
These amounts are for a base mix. We need to use these to find out how much of each color is necessary to make a larger total amount of dye.
a. If the stylist needs to make 20 oz of dye:
1. First, you convert [tex]\(1 \frac{1}{8}\)[/tex] oz to an improper fraction. So, [tex]\(1 \frac{1}{8} = \frac{9}{8}\)[/tex].
2. Calculate how much of each tone is needed for 20 oz:
- Red tone: [tex]\(\frac{9}{8} \times 20 = 22.5\)[/tex] oz
- Gray tone: [tex]\(\frac{3}{4} \times 20 = 15\)[/tex] oz
- Brown tone: [tex]\(\frac{5}{8} \times 20 = 12.5\)[/tex] oz
b. If the stylist needs to make 100 oz of dye:
1. Again, using the ratio fractions:
2. Calculate how much of each tone is needed for 100 oz:
- Red tone: [tex]\(\frac{9}{8} \times 100 = 112.5\)[/tex] oz
- Gray tone: [tex]\(\frac{3}{4} \times 100 = 75\)[/tex] oz
- Brown tone: [tex]\(\frac{5}{8} \times 100 = 62.5\)[/tex] oz
In summary, to make:
- 20 oz of dye, you'll need 22.5 oz of red, 15 oz of gray, and 12.5 oz of brown.
- 100 oz of dye, you'll need 112.5 oz of red, 75 oz of gray, and 62.5 oz of brown.
