Martin find a shirt on sale for 10% off at a department store the original price was $20 Martin must also pay 8.5% sales tax how much is the shirt before taxes are applied

Respuesta :

first change the percent to a decimal 10% = 0.1  8.5% = 0.085
then subtract 20 - 0.1 = 19.9
then add 19.9 + 0.085 = 19.985
hope it help ☺
