The formula for simple interest is <em>I</em> = <em>prt</em>, where <em>I </em>is the amount of interest, <em>p</em> is the principal invested, <em>r</em> is the rate as a decimal number and <em>t</em> is the amount of time. Substituting our given information we have
128 = <em>p</em>(0.016)(2) ----- 1.6% = 1.6/100 = 0.016
128 = <em>p</em>(0.032)
Divide both sides by 0.032:
128/0.032 = <em>p</em>(0.032)/0.032
4000 = <em>p</em>
He needs to invest $4000.

Find out the area of the countertop in square meters .
To proof
As given
A countertop is 16ft long & 3ft wide.
A countertop is in the shape of the rectangle.
FORMULA
Area of a rectangle = length × breadth
long = 16ft
wide = 3ft
put the value
we get
Area of a countertop = 16 ×3
= 48 feet²
1 meter = 3.281 feet

convert Area of a countertop in square meters

= 4.461 m² ( approx )
Hence proved
