16+64=80 80*2=160
or it means
64/2=32 32+16= 48

64+16=80 80/2= 40
this is a horribly formatted question

Answer:
i think that is 147
Step-by-step explanation:
6+2(x+8)+3x+11+x
First you have to expand the brackets:
6+2x+16+3x+11+x
Now you group like terms (terms with the same or no variable):
2x+3x+x+11+16+6
And finally, combine like terms:
6x+33
Hope this helps :)
Answer:
First, 3 people divide $30, then each one of them pays:
$30/3 = $10.
Each one of them gets $1 in refound.
Then at the moment, each one of them paid $9, and there are 3 friends, so the total amount is 3*$9 = $27.
We also know that the cashier keeps $2, but these $2 must come from the $27 that the friends paid.
Then we will have $27 = $25 + $2.
This means that the total cost was $25, and the cashier kept $2 as a tip.
Now, in your problem, you add the $2 that the cashier kept to the $27 that the friends paid. While those $2 actually are already counted in the $27 that the friends paid.
