Answer:

Charlene earns $700 per week

Kristi earns $550 per week

Sascha earns $800 per week

Step-by-step explanation:

Since Kristi earns 150 less than Charlene which is 100 less than Sascha, this is equal to the value of Sascha minus 250. We put this in the equation as s-250.

Together, they all earn $2050, so we must equal this to Charlene's value k+150, plus Kristi's value k, plus Sascha's value s.

<em>k+150+k+s=2050</em>

The next step here is to put the variables on one side and to put the numeric values on the other.

2k+s=1900

Like we said before, Kristi's value is equal to s-250, so we would replace k with that expression.

2(s-250)+s=1900

2s-500+s=1900

3s=2400

s= 800

We now have Sandra's weekly pay, which we can use to find the others' pay.

c= s-100

c= 800-100

c= 700

k= c-150

k= 700-150

k= 550

On a quiz, students were awarded a certain number of points for a correct answer and penalized a certain number of points for an
SVETLANKA909090 [29]
Given that the score of the student on the quiz was 25c - 10(15 - c)

It can be seen that the first term of expression for her score (i.e. 25c) shows that 25 marks were awarded to each correct answer.

The second term of the expression (i.e. 10(15 - c)) represent that 10 marks were deducted from each wrong answer.

Thus, the number of wrong answers is 15 - c.

The sum of the correct answers and the wrong answers gives the total number of questions in the quiz.

Thus, the total number of questions in the quiz is given by 15 - c + c = 15.

Therefore, there are 15 questions in the quiz.
