Answer:
$306
Step-by-step explanation:
First you make it into fractions. 1/300 = 2/100
The 2 in the fraction represents the tax rate over 100
The 300 represents the microscope price.
Now multiply the 300 and 2 and 1 and 100
300 x 2 & 1 x 100
600 & 100
Now divide these two
Now you have 6
The 6 is the tax
So now add 300 + 6
$306
