myHostname = window.location.hostname;
var myTLD = "." + myHostname.substring(myHostname.indexOf("wupload") + "wupload.".length).split(".")[0];
function afterLoad() {
return
}
ieFixForFileSelectionOnChangeEventTimer = null;
function ieFixForFileSelectionOnChangeEvent(a) {
$("#siteName").toggle();
if ($("#inputFileSelection").val() == "") {
ieFixForFileSelectionOnChangeEventTimer = setTimeout("ieFixForFileSelectionOnChangeEvent()", 200)
} else {
$("body")[0].focus()
}
}
function urlencode(a) {
return escape(a.toString().replace(/%/g, "%25").replace(/\+/g, "%2B")).replace(/%25/g, "%")
}
The area is 4 square meters, because 2x2 would be 4
N + d = 20....n = 20 - d
0.05n + 0.10d = 1.35
0.05(20 - d) + 0.10n = 1.35
1 - 0.05d + 0.10d = 1.35
-0.05d + 0.10d = 1.35 - 1
0.05d = 0.35
d = 0.35/0.05
d = 7 <==== 7 dimes
n + d = 20
n + 7 = 20
n = 20 - 7
n = 13 <=== 13 nickels
