Answer:6
Step-by-step explanation:
using BIDMAS: Brackets,Indices,division,multiplication,addition,subtraction.
1) Firstly you do the problem in the brackets. (-19 - -20) two negatives next to each other make a plus(+) meaning (-19 - -20) = (-19+20) which = 1
2) Next Step is to do the multiplication section. Since we got 1 in place instead of (-19 - -20) we multiply -3 by 1 which = -3.
3) Now the equation we have is 11 + -8 - -3. In BIDMAS both addition and subtraction are equal therefore we can do it in any order. 11 + -8 is the same as 11 - 8 = 3
4) The problem we have now is 3 - -3, like we said before two negatives next to each other make an addition sign(+) so 3 - -3 = 3+3 = 6, therefore getting the answer 6.

Answer:
No, it's actually 100

If you put brackets in the right places you'll see (3*20)+(4*10)=60+40=100
Answer:
The total change is £21.02 from the original amount of £78.98. Therefore, the percentage change is directly related to the original amount.
Divide the total change by the original amount to determine the percentage change the new amount represents.
21.02÷78.98=0.15219 which rounds up to two decimal places as 15.22%.
