The sales tax rate ib jans town is 7.5% if she buys 3 lamps for 23.59 each and a sofa for 768.99 how much sales tax doas she owe

Respuesta :

the total price of all 3 lamps without the sales tax= $70.77
add the price of the sofa 
$70.77+$769.99= $840.76
the tax is going to be added on to the total price
multiplying the $840.76 by .075 (which is the sales tax)
the total she owes= $63.05
