Answer: Its True
Step-by-step explanation:
The statement is true because the Percentages are preferred and also they are easier to compare than counts.
Mary Purchase shares = $80,000
Mary Sells shares = $55,000
Loss she can claim for = $80,000 - $55,000
= $ 25,000
A, c, and d
plug in each x in the equation and it should equal the y value
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.
