Myra bought a pair of jeans that cost $55. The sales tax rate is 10 percent. What is the total amount she paid for the jeans?
Semmy [17]
You need to calculate the sale tax and add it to the value of the pair of pants. The tax is calculated by multiplying the cost of the pants times the rate, i.e.tax = $55 * 10% = $55 * 10/100 = $ 55*0.1 = $ 5.5. Now sum this tax to the cost of the pants: $ 55 + $5.5 = $ 60.5. Then, the answer is $ 60.50
