A salesperson set a goal to earn $3,000 in July. He receives a base salary of $1,200 per month as well as a 10% commission for all sales in that month. How many dollars of merchandise will he have to sell to meet his goal?

Answers

Answer:

$18,000


Step-by-step explanation:

Target is 3000, out of which 1200 will already be earned from salary. So he needs 3000 - 1200 = 1800 from commissions.


As we know, 10% is the commission rate, we need to know "Which numbers' 10% will give us 1800??"


Thus let total sales be x, so we can write 0.1x=18,000

Solving gives us:

0.1x=1800\nx=(1800)/(0.1)=18,000


He needs to sell $18,000 worth of merchandise to meet his income target for July.

Well, the commission should total $1,800. This is one tenth of what he sells, so he must sell $18,000 value of merchandise.

Paolo pays $244 for 5 identical calculators. About how much does Paolo pay for one calculator?

Answers

About $50 because if you round 244 to 250 (because 250 is easier to dived into 5 and is close to 244). Then you dived 250 into 5 which equals 50.
so you are going to add and it will be 30 for your answer

Which of the following are solutions to the equation below? Check all that apply. 9x^2-64=0A. 8
B. -8
C. -3/8
D. 3/8
E. -8/3
F. 8/3

Answers

Answer:

E. -8/3

F. 8/3

Step-by-step explanation:

9x^2-64=0

Add 64 to each side

9x^2-64+64 = 0+64

9x^2 =64

Divide each side by 9

9x^2/9 = 64/9

x^2 = 64/9

Take the square root of each side

sqrt(x^2) = ±sqrt(64/9)

We know that sqrt(a/b) = sqrt(a)/sqrt(b)

x = ±sqrt(64)/sqrt(9)

x = ± 8/3

in class, matthew stated "i think that a negative is like an opposite. That is why multiplying a negative times a negative equals a positive. The opposite of negative is positive, so it is just like multiplying the opposite of a negative twice, which is two positives." Do you agree or disagree with this statement? What would you say in response to him?

Answers

Answer: Yes, I agree with this statement.

Step-by-step explanation:

Yes, I agree with this statement.

Whenever we multiply two negative numbers, we get a positive number.

As two negatives makes a positive.

Negative is just like an opposite.

Opposite of 4 is -4.

and negative of 4 is also -4.

The opposite of negative is positive.

i.e. opposite of -4 is 4.

So, Negative is always treat as opposite.

Yes and no. A negative number and it's opposite are 'integers.' Yes, a negative and a negative multiplied together give you a positive. The two negative signs cancel out making it positive. But no, a positive and a positive multiplied together do not give you a negative. When you subtract positive numbers you can get a negative, but not when multiplying. If you were to do a positive times a negative it would be negative because the positive can't cancel it out. Example: -3 · -3 = 9. [] 3 · 3 = 9. [] -3 · 3 = -9. Other than the positive number part, the statement is true about the negatives. I hope that helped!
