They have just halved 48
Instead as it says they should do 2 x 48 which is 96
As there are 96 halves within 48
The answer is 400 because 40.00*8.5 is 340.00. Add on the 60 dollar service charge and get 400.00.

First, change the fractions to a common denominator, which is 21.
so 3/7 * 3/3 = 9/21
1/3 * 7/7 = 7/21
Add the two together
9/21 + 7/21 = 16/21
Then take 21/21 - 16/21 = 5/21
There is 5/21 of the pizza left.
