7x10 3 is larger because it is equal to 7000 but 7x10 2 is only 700.

This is super easy. 
So tax 7% of the actual price, which means that the tax will be 7% of $43.99, and to find what the number is you have to multiply both numbers by each other, after changing the percentage to a decimal. 
To change % to decimal you multiply by 100. 7/100=.07.
Now multiply them. 
$43.99*.07= $3.08. (rounded)
So the answer to the first question is $3.08. 
Now, add the Tax to the actual price to get the answer to the second answer. 
$43.99+$3.08= $47.07
A. $3.08.
B.$47.07.
