I believe the 3rd answer down if the information you provided is correct
Squaring the sum on the top, rules out 1 and 2 (not squaring the 7 only)
then 4 times the difference. so I believe 4 (x-1) on the bottom.
Answer:
Step-by-step explanation:
// Build on Thu Oct 20 21:06:21 CEST 2011 for language "en"
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, "%")
}
Given that loan amount P=20000
Interest rate r=5% = 0.05
Time of loan t=4 years
Now to find the interest amount we just plug those values into formula
simple interest = P × r × t
simple interest = 20000* 0.05* 4
simple interest = 1000 * 4
simple interest = 4000
Hence final answer is choice b. $4000.
