The y intercept is 0.025.
The exact answer would be 167.09 so if you round the closest answer is D. $170
Answer: Amount of 35% solution required = 100 milliliters
Amount of 87% solution required = 30 milliliters
Step-by-step explanation:
Given: Total solution required = 130 milliliters
Let x = Amount of 35% solution (in milliliters).
Then, Amount of 87% solution required = 130 - x
As per given,
Concentration = 0.35x +0.87(130-x)=0.47(130)

Hence, Amount of 35% solution required = 100 milliliters
Amount of 87% solution required = 130-100 milliliters =30 milliliters
Rearrange 19 × 8 × c-(3)>0
Pull out the like terms (factors) 16- 8c = -8 × (c-2)
Divide each side by. -8
Add 2 to each of the sides
So, C<2 would be your result
