First, to estimate we can round 53.82 up to 55.00. Then you can look at it like this: when you divide 100 by 20 you get 5, so 20% is one fifth of 100. Therefore, we want to find one fifth of $55. To do this, you multiply 55*1/5. When you multiply the numerators by each other and the denominators by each other, you get 55/5. When you divide the numerator and denominator by 5, you get 11/1 or $11.

Step-by-step explanation:
Following the order of operations we would first divide -30 by 5 which would give us -6
-6 + (-30) ÷ 5 - (-2)
From here we can add -6 + -6 = -12
-6 + (-6) - (-2)
When subtracting a negative number, the two negatives changes it to a positive. (-12) - (-2) = (-12) + 2 which would give us -10
(-12) - (-2) = -10
