Ollie earns a fixed amount of $2,700 per month and a commission of 12% on all of his sales for the month. To cover all of his ex

storchak [24]

Answer:

Part A) $0.12x+2,700\geq 5,400$

Part B) see the explanation

Step-by-step explanation:

Part A) Write an inequality that will represent the amount of sales Ollie will need in order to cover his monthly expenses

Let

x ----> the amount of sales monthly

Remember that

$12\%=12/100=0.12$

we know that

The fixed amount of $2,700 plus the commission of 12% on all of his sales for the month must be greater than or equal to $5,400

The inequality that represent this problem is

$0.12x+2,700\geq 5,400$

Part B) Find the solution and describe what the graph would look like on a number line

we have

$0.12x+2,700\geq 5,400$

Solve for x

subtract 2,700 both sides

$0.12x \geq 5,400-2,700\\0.12x \geq 2,700$

Divide by 0.12 both sides

$x\geq \$22,500$

The minimum amount of sales needed to cover his monthly expenses is $22,500

In a number line the solution is the shaded area at right of x=22,500 (closed circle)

a lab technician mixed a 690 ml solution of water and alcohol, if 3% of the solution is alcohol, how many milliliters of alcohol

neonofarm [45]

To get the milliliters of alcohol used, we must multiply 690 by 0.03. If we do this, we will get 20.70, which means that 20.70 milliliters of alcohol were used. On the other hand, we can get the milliliters of water used through two ways: the first one is by simply subtracting 20.70 from 690, which will give us the answer 669.30. Another would be by multiplying 690 by 0.97, which will also yield the answer 669.30. The number of milliliters of water used was 669.30.
