You can put this solution on YOUR website! sol:
sales price=marked price (or) selling price+sales tax
sales price of toyota corolla=$15,714
rate of sale tax=8%=8/100
sales tax=rate of sales tax*marked price (or) selling price
let selling price be x
sales tax=(8/100)*x
sales tax=8x/100
sales price=selling price+sales tax
$15,714=x+8x/100
multiplying by 100 on both sides
$15,714*100=100*x+(8x/100)*100
$15,714*100=100x+8x
15,714*100=108x
dividing by 108 on both sides
(15,714*100)/108=108x/108
15,714*100/108=x
x=1571400/108
x=14,550
selling price=14,550
