The total bill (before tax and tip) = $90
Tax = 6% = 0.06
0.06 x $90 = $5.4
Tip = 20% = 0.20
0.20 x $90 = $18
$90 + $18 + $5.4 = $113.4 (Answer)
Answer:
= -43
Step-by-step explanation:
Evaluating the expression;
(–1)8 + (–1)7 + –16 + –14 – (–1)2
We can use Bodmas
We remove the brackets first
(–1)8 + (–1)7 + –16 + –14 – (–1)2
We get
-8 + - 7 + -16 + -14 - -2
but; - × + = - and - × - = +
Thus;
-8 - 7 - 16 - 14 + 2
= -8 -7 - 16 - 12
<u>= -43 </u>
