I went to the grocery store and my subtotal was $78.00. There is a 4.5% sales tax. How much is my total grocery bill including tax

81.51

Step-by-step explanation:

So first you will want to take the percentage of the $78.00.

What we do is multiply 78.00 by 0.045

which is 4.5%

You then get $3.51

Add that to the $78.00:

78.00 + 3.51

= $81.51
