At the end of 3 years, how much money would you have in total if you invested $75 and earned 5% simple interest?
a.
$86.25
b.
$90
c.
$100.25
d.
$105

A.  $86.25

Step-by-step explanation:

The formula to calculate the simple interest is given by :-

, P is Principal amount , r is rate of interest and t is time.

Given : P= $75   ;  r= 5%=0.05 ;    t=3 years

Then, the simple interest will be:-

Now, the money you have after 3years = P+I = $75+$11.25=$86.25

Hence, you would have $86.25 at the end of 3 years.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
