The total cost of the dinner is $176.20
Here, we want to calculate the total cost of the dinner
To calculate this total cost, we need to identify the parts necessary
These parts of the bill are;
a) Main cost of dinner
b) sales tax
c) Tip
By calculating and adding all of these, we get the total dinner cost
a) This is $140 from the question
b) This is 8% of the dinner cost which is 8% of 140
Mathematically, we have that as;
[tex]\begin{gathered} \frac{8}{100}\text{ }\times\text{ 140} \\ \\ =\text{ \$11.20} \end{gathered}[/tex]c) The tip cost which is $25
The total cost of the dinner is thus;
[tex]a\text{ + b + c = \$140 + \$11.20 + \$25 = \$176.20}[/tex]
