Answer:
$31.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1.5%/100 = 0.015 per year,
then, solving our equation
I = 700 × 0.015 × 3 = 31.5
I = $ 31.50
The simple interest accumulated
on a principal of $ 700.00
at a rate of 1.5% per year
for 3 years is $ 31.50.
This equation basically says that a number plus 3/5 equals 2 so we can simply:
2 - 3/5 = x
Therefore x equals 1 & 2/5 or 1.4
