Can u guys tell me the answer to question 8 and 9 thank you so much I would really appreciate it
Thank you

Step-by-step explanation:

Q8.  

Step 1.

35.4 - 31 = 4.4

Step 2.

4.4 ÷ 31 = 0.1419

Step 3.

0.1419 x 100 = 14.19...

Step 4.

To one decimal place = 14.2% increase

Q9.

Step 1.

£10 ÷ 40 articles = £0.25 = 25p (this is the answer to part a)

Step 2.

32p x 40 articles = £0.32 x 40 articles = £12.80 (this is the answer to part b)

Step 3.

£12.80 - £10 = £2.80 (this is the answer to part c)

Step 4.

£2.80 ÷ £10 = 0.28

Step 5.

0.28 x 100 = 28% (this is the answer to part d)
