Answer:
$3.77
Step-by-step explanation:
The formula for the percentage of an amount is : 
To work out the value of the tax you would first need to convert the percentage of 6.5 into a decimal. You can do this by dividing the percentage of 6.5 by 100, this gives you 0.065. This is because percentages are out of 100.
The next step is to multiply 0.065 by the amount of $58, this gives you 3.77. This is because we are working out 6.5% of $58 and so would multiply the decimal by the amount to work that out.
1) Divide 6.5 by 100.

2) Multiply 0.65 by 58.
