Food bill before tax $30 sales tax 6.4% tip 15%

Total Bill is $36.71

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Firstly, we should convert the percentages into decimal form by moving the decimal 2 digits to the left.

Tax: 6.4%   ⇒   0.064

Tip:  15.0%    ⇒   0.15

Now we start by multiplying the food bill before tax by (1 plus sales tax). Like so,

30 * (1+0.064) =  31.92

Now all that is left is to calculate and add the tip by multiplying this new total by (1+15% tip)

31.92 * (1+0.15) = 36.708

Finally, we can see that the Total Bill is $36.71
