The answer is $2,424.80
The total balance in Kimmy account in December is $468.98
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
In June, Kimmys savings account has a balance of $76.23.
And, By September, her balance is 5 times as much as her June balance.
Between September and December, Kimmy deposits a total of $87.83 into her account.
Now,
Since, In June, Kimmys savings account has a balance of $76.23.
And, By September, her balance is 5 times as much as her June balance.
So, The account balance in September = 5 x $76.23
= $381.15
And, Between September and December, Kimmy deposits a total of $87.83 into her account.
So, The account balance in December = $381.15 + $87.83
= $468.98
Thus, The total balance in Kimmy account in December is $468.98

The correct answer is:
$468.98.
Explanation:
The account balance in June is 76.23. Since the value in September is 5 times that, the September balance is 5(76.23) = 381.15.
She deposits 87.83 between September and December; this makes the total 381.15+87.83 = $468.98.

Answer:
Volume of Mixture A =90 ml
Volume of Mixture B =30 ml
Step-by-step explanation:
Let say, Mixture A + Mixture B = Mixture C
Volume of Mixture A is x
Volume of Mixture B is y
So, Volume of Mixture C is x+y = 120 ml
Now, Acid contain in Mixture A is 20% =0.2x
Acid contain in Mixture B is 80% =0.8y
Also, Acid contain in Mixture C is 35% =(0.35)(x+y) = 0.35×120=42
Now, we know that,
Acid contain of Mixture A + Acid contain of Mixture B=Acid contain of Mixture C
∴ 0.2x+0.8y=42
∴ 2x+8y=420
We get two linear equations
2x+8y=420 and x+y = 120
Solving above equation...
∴ x=120-y
Replacing x value in 2x+8y=420
∴ 2(120-y)+8y=420
∴ 240-2y+8y=420
∴ 6y=180
∴ y=30
Replacing y value in any equation
∴ x=120-y=120-30=90
∴ x=90
Thus,
Volume of Mixture A is x=90 ml
Volume of Mixture B is y=30 ml
