Final answer:
To find the sales tax, convert the rate to a decimal and multiply it by the total cost of the item. In this case, Ms. Mollins pays $6.38 for the sales tax.
Step-by-step explanation:
To find the sales tax, we first need to convert the sales tax rate to a decimal. In this case, the sales tax rate is 7.5%, so we divide by 100 to get 0.075. Then, we multiply the total cost of the jacket, which is $85, by the sales tax rate:
$85 x 0.075 = $6.375
Since we are rounding to the nearest cent, the sales tax is $6.38. Therefore, Ms. Mollins pays $6.38 for the sales tax.
