Question

If you go out to eat with 3 friends and your meal was $72.50, there is 6.75% sales tax
and you should tip the waiter 15%. How much should each person pay

Answer 1

6.75% of 72.50

=6.75/100×72.50

=$4.89375 is sales tax

15% of 72.50

= 15/100×72.50

= $10.875 is tip

So Total amount = 10.875+4.89375+72.50

= $ 88.26875

Then as total people are 4

Therefore, 88.26875/4 = $22.0671875

Thus each one has to pay $ 22.0671875

Answer 2

Given cost of meal, sales tax and tip payable, find the share of each person

Explanation:

1. let the total amount payable be 'T', cost of meal be 'm', taxable amount be 't' and tip payable be 'a', then we have                                                            $T=m+a+t$                                  $(given\ m=\ 72.5)$                                                                              
2. given the tax percentage 'x' the taxable amount is given as ,                                $t=m\frac{x}{100}=72.5\frac{6.75}{100} \\t=\ 4.89375$      
3. given the tip percentage 'y' the tip payable amount is given as,                               $a=m\frac{y}{100} =72.5\frac{15}{100} \\a=\ 10.875$  
4. putting these values in equation from point 1. we get,                                                     $T=72.5+4.89375+10.875\\T=88.26875\ \ \ \ \\T=\ 88.3(approx.)$    
5. now, the amount payable by each person (total four people) is                                $A=\frac{T}{4}=\frac{88.3}{4} \\A=\ 22.75$     ---->ANSWER
