Raven should buy the boots at LaceUp since total cost is lower ($77.54)
Step-by-step explanation:
price of the boots at Shoe Town:
[$85.95 x (1 - 15%)] x (1 + 7.16%) = $73.06 x 1.0716 = $78.29
price of the boots at LaceUp:
{[$85.95 x (1 - 10%)] - $5} x (1 + 7.16%) = ($77.36 - $5) x 1.0716 = $72.36 x 1.0716 = $77.54
price of the boots at Run, Don't Walk (online store):
$71.99 + $6.50 = $78.49
