luis wants to uy a skateboard that usually sells for $79.99. all merchandise is discounted by 12%. what is the total cost of the skateboard if luis has to pay a state sales tax of 6.75%.

Respuesta :

$75.14. formula as follows ($79.99 - (($79.99/100)x12)) + ((($79.99/100)x12)/100)*6.75)

$77.28 if u take away 12% of 79.99 and then u add 6.75% it comes up to 77.28
