Answer
Total cost of the towels is $79.19.
Work Step by Step
Total cost includes the price of the towels multiplied by 5, sales tax on that amount at a rate of 5%, and the cost of shipping based on the cost of the towels.
$c=12.99\times5=64.95$
$t=64.95\times0.05=3.25$
Shipping is 10.99 for items costing between 50.01 and 70.00.
$tc=64.95+3.25+10.99=79.19$
