Gabby bought a backpack and 3 notebooks for $40.66. What is the total tax if the rate is 8%?

$3.24

Step-by-step explanation:

You would first have to figure out the cost of each notebook with tax so you would divide 40.66 by 3

40.66/3 = 13.55

So each notebook costs $13.55 with tax. Now, I multiplied 13.55 by 0.08. I would multiply it by 0.08 because 8% in decimal form is 0.08.

13.55*0.08 = 1.08

I got the answer 1.08. 1.08 is the tax for each notebook so I would multiply it by 3 to figure out the total tax.

1.08*3 = 3.24

Hence, the total tax is $3.24.

Hope this helped :-)
