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.

A costumer bought some potting soil for $12.50 and 6 shrubs.
If the total bill was $71.00, you can calculate how much did each shrub cost if they all cost the same:
$71.00 - $12.50 = $58.5
$58.5 / 6 shrubs = $9.75
Result: Each shrub cost $9.75.
