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
Answer:
- 45 large candles
- 53 small candles
Step-by-step explanation:
Let c represent the number of large candles Jane sold. Then 98-c is the number of small candles. Her revenue is ...
8c +5(98-c) = 625
3c + 490 = 625 . . . . . . eliminate parentheses, collect terms
3c = 135 . . . . . . . . . . . . subtract 490
c = 45 . . . . . . . . . . . . . . divide by 3
Jane sold 45 large candles and 98-45 = 53 small candles.
We can multiply the 4 and 7 together.
28 * n
