I would say the best estimate would be 9 because the real answer is 8.71 and if you round that to the 1 place the answer would be 9.
I think the answer is 20 but I'm not sure
Your answer would be -22 = -18
$21.44•.25=$5.36
So if you are asking just how much the shipping and handling is it’s $5.36 but if you are asking the total it’s. $26.80
$21.44+$5.36=$26.80
