Answer: 4.8 liters
Step-by-step explanation:
Let x liter of water is added with y liter of 25% beach solution.
Thus, According to the question,
x + y = 12 -------(1)
0% of x + 25 % of y = 15 % of 12
25 % of y = 15% of 12
Put this value in equation (1),
We get,
Therefore, the quantity of water = 
And, the quantity of 25% bleach solution = 
Answer:The simple interest rate is 7.50%
Step-by-step explanation:
Simple interest, I =( P × T × R) / 100
Where P= Principal investment
T = Time in years
R = rate
Given
P= 981.60
I = 1000 - 981.60 = 18 .40
T = 13 weeks = 13 / 52 = 0.25 year
I =( P × T × R) / 100
Cross multiply
I × 100 = P × T × R
18.40 × 100 = 981.60 × 0.25 × R
1840 = 245.4 R
R= 1840 / 245.4
R = 7.498%
To the nearest tenth
R = 7.50%
