Answer:
q5. £40.50
q6. didn't know that one sorry
q7. $114.24
Step-by-step explanation:
q5. 55% of £90
10% = 9
5% = 4.5
to get to 50% you do 10% x 5 = 50%
you then do 9 x 5 = 45
after that you add the 45 + 4.5 = 49 .50
after that you do £90 - 49.50 = £40.50
q7. 12% of 102
10% = 10.2
1% = 1.02
2% = 2.04
12% = 10.2 + 2.04 = 12.24
then you do 102 + 12.24 = 114.24
