Question 1:
------------------------

Total points = 100
Total question = 40
Type of questions : 2-points question and 4-points questions

Assumed all 40 questions are 2-points questions.
Total points = 40 x 2 = 80

Difference in points = 100 - 80 = 20 points
Difference in the 2 type of questions = 4 - 2 = 2

Number of 4 marks questions = 20 ÷ 2 = 10 

Number of 2 marks questions = 40 - 10 = 30

Answer: There are 10 4-marks questions and 30 2-marks questions.

------------------------------------------------------------------------------------------------

Question 2:
------------------------

Let x be the number of offices you need to clean.

Total cost = 315 + 4x
Total revenue = 25x

To break even,
315 + 4x = 25x
21x = 315
x = 15

Answer: You need to clean 15 offices to break even.

------------------------------------------------------------------------------------------------

Question 3:
------------------------

Total distance (including return trip) = 255 + 255 = 510 miles

Total time taken = 1.7 + 1.5 = 3.2 hours

Speed = Distance ÷ time

Speed = 510 ÷ 3.2 = 159.38 miles/hour

Answer: The average speed is 159.38 miles/hour

Decrease £120 by 15%
Irina-Kira [14]

To decrease this amount by 15% we must first find out what is 15% percent.

We can do that by multiplying the decimal of 15% by 120

15% = 0.15

0.15 x 120 = 18

So 18 is 15% of 120.

Wait! that's not the answer. We are asked to decrease by 15%

So 120 - 18 = 102

Your answer is £102
