Answer: sales tax rate is 5%
Step-by-step explanation:
Item x sales tax (in decimal form) = total sales tax.
Card before tax=$ 12
Card after tax= $12.6
Difference = $0.6
Take the difference and divide it by the total price: $0.6 ÷ $12.6
=0.0476
Convert the decimal into a percentage by moving the decimal point two places to the right: .0476 becomes 5%
Your original sales tax rate is 5%
