What do we know from the problem?:
*bill is $58
*wants to leave 80% tip
what's missing?:
what's the total bill
How to solve it?:
first we have to take care of the 80% so..
80/100= 0.80 or 0.8
step 2:
$58 x 0.8= $46.40
Step 3:
ADD the total bill which is $58 and add the $46.40
$58 + $46.40= $104.4
FINALLY: Arun's total bill was $104.40

$150 divided amongst himself and friends (3) which equals 50, so add $50 to Sam’s share.
Answer:
195.65
Step-by-step explanation:
C^2= a^2 + b^2
putting values
(8)^2= (4)^2+B^2
64=16+B^2
64_16=b^2
48=b^2
b=√48
