Answer:
Volume of 3% alcohol = 80 ml
Volume of 8% alcohol = 120 ml
Step-by-step explanation:
Final volume of 6% alcohol solution = 200 ml
Let the volume of 3% alcohol volume = a ml
Therefore, volume of 8% alcohol = (200 - a) ml
Equation for the given situation will be,
3a + 8(200 - a) = 6×200
3a + 1600 - 8a = 1200
1600 - 5a = 1200
5a = 400
a = 80 ml
Therefore, volume of 3% alcohol to be used = 80 ml
And volume of 8% alcohol to be used = (200 - 80) = 120 ml
Answer:

Step-by-step explanation:
Given : Marsha has budgeted no more than $3,000 on centerpieces for the tables
x denotes the number of Guest Tables Lily Arrangements
y denotes the number of Family Table Rose Arrangements
To Find: Which inequality represents all possible combinations of x, and y, that Marsha can buy for no more than $3,000?
Solution :
Since there are x number of Guest Tables Lily Arrangements.
And there are y number of Family Table Rose Arrangements
Since she cannot spend more than 3000 on centerpieces .
So, the inequality becomes:

Hence inequality represents all possible combinations of x and y that Marsha can buy for no more than $3,000:
