A company produces fruity drinks that contain a percentage of real fruit juice. Drink A contains 20% real fruit juice and Drink
Setler [38]

Answer:

There needs to be 300 liters of Drink A and 270 liters of Drink B

Step-by-step explanation:

Let a = the amount of Drink A and b = the amount of Drink B

Multiplying a number by 0.2 is the same as calculating 20% of it and same goes with 15% and 0.15. This makes our equation for the amount of fruit juice:

0.2a + 0.15b = 100.5

We know what the difference between a and b will be 30 liters so:

a - b = 30

Now we have our system of equations

To cancel out a, we can multiply the first equation by -5 so we will now have:

-a - 0.75b = -502.5

a - b = 30

Adding these two equations together, we get:

-1.75b = -472.5

Both sides are negative, so we can take the negative signs away.

1.75b = 472.5

Now divide both sides by 1.75

b = 270

Plugging 270 into b, we have:

a - b = 30

a - 270 = 30

Add 270 to both sides

a = 300

There needs to be 300 liters of Drink A and 270 liters of Drink B

Alexa has finished her culinary training program and is now working full-time as a chef in a hotel resort restaurant. She has tr
otez555 [7]

Answer: The budget of Alexa is increased by $100.

Explanation:

It is given that the current income of Alexa is 3 times of her previous income.

Her previous salary was $800 and current salary was $2400.

Expenses =   Rent  + Utilities  + Groceries  + Savings  + Bus

The sum of previous expenses is,

Previous expenses = $300 + $60 + $200 + $100 + $30 = $690

The sum of current expenses is,

Current expenses = $300 + $60 + $250 + $150+ $30 = $790

Effect of income on expenses is the difference of current expenses and previous expenses.

Effect of income on expenses = $790 - $690 = $100

Therefore, the budget of Alexa is increased by $100.
