How much water should be added to 5 gallons of 50% acid solution to get a 20% solution?

erastovalidia [21]

This question is based on the concept of solving an equation. Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

Given:

5 gallons of 50% acid solution to get a 20% solution.

According to question,

Let it be x gallons of water should be added to 5 gallons of 50% acid solution to get a 20% solution.

Now, forming the equation, we get,

0.50 ( 5 ) = 0.20 ( x + 5 )

Simplifying the equation.

We get,

2.5 = 0.2x + 1

1.5 = 0.2 x

x = 7.5

Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

Mimi sells super-sized cookies for $1.50 each and estimates she has expenses of $10 to make one batch of cookies. If the inequal

Jobisdone [24]

Answer:

(b) x > 26 cookies

Step-by-step explanation:

The selling price of 1 super-sized cookie, S.P.=$1.50

Let a batch have x cookies.

So, the selling price of x cookies=1.5x

The expences in making one batch of cookies=$10

So, net profit = 1.5x-10

The given inequality to model this is 1.5x - 10 > y, That means the profit for one batch is greater than y.

As she wants to make a profit of at least $30, so for this condition, the value of y is 30.

Now, the given inequality become,

$1.5x - 10 >30$

$\Rightarrow 1.5x>30+10$

$\Rightarrow x>\frac{40}{1.5}$

$\Rightarrow x>26\frac{2}{3}$

As x is the number of cookies, so, it can't have a fractional value. This can be written as

$x>26$ or $x\geq27.$

So, she has to sell more than 26 cookies to make a profit of at least $30.

Hence, option (b) is correct.
