A group of 8 friends went to lunch and spent a total of $76, which included the food bill and a tip of $16. They decided to spli
Rudik [331]

Answer:

1) The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.

2) The solution x=60 represents the total food bill.

These both answers are correct.

Step-by-step explanation:

Since there are 8 group of friends, and the total amount spent by them is $76 including the tip i.e $16.

If x is the food bill our equation can be:

(x+16)/8 = 76/8

Solving the equation

(x+16)/8 = 9.5

x+16= 9.5*8

x= 76 -16

x= 60

The food bill is x=60.

Find the present balance.
Triss [41]
<h3>Credited balance:-</h3>

\\ \rm\longmapsto 115.90+115.90+345.85

\\ \rm\longmapsto 231.80+345.85

\\ \rm\longmapsto 577.65

<h3>Debited amount:-</h3>

\\ \rm\longmapsto 25.85+2.00

\\ \rm\longmapsto 27.85

<h3>Checked amount:-</h3>

\\ \rm\longmapsto 19.45+21.02+95.98

\\ \rm\longmapsto 117+19.45

\\ \rm\longmapsto 136.45

<h3>Total change in balance</h3>

\\ \rm\longmapsto 577.65-(27.85+136.45)

\\ \rm\longmapsto 577.65-191.3

\\ \rm\longmapsto 386.35

Now

<h3>Current balance</h3>

\\ \rm\longmapsto 386.35+271.31

\\ \rm\longmapsto\$ 657.66
