$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
Well 43 ones times 3 tens is basically 43 times 30 which is 1,290 then divide that by ten to get how many tens and you will get 129 tens hope this helps
