1) The scenario is represented by the equation 1/8(x+16)=76/8, where x is the food bill.
2) The total food bill is represented by the equation x=60.
Both of these responses are correct.
Step-by-step instructions:
Because there are eight buddies in the group, the total money spent by them is $76 (including the $16 tip).
Our equation can be as follows if x is the food bill:
76/8 = (x+16)/8
Solving the Problem
9.5 = (x+16)/8
9.5*8 Equals x+16
x=76 -16 x=76 -16 x=76 -16 x=
60 = x
The cost of food is x=60.

To get the growth factor from a percentage increase, express the percentage as a decimal, then add 1.
256% = 2.56
2.56 + 1 = 3.56
The appropriate choice is ...
