Answer:
$280
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year,
then, solving our equation
I = 2800 × 0.02 × 5 = 280
I = $ 280.00
The simple interest accumulated
on a principal of $ 2,800.00
at a rate of 2% per year
for 5 years is $ 280.00.
True, there are 2 y's and 3 x's

So since that is the measurement of 1 marathon, therefore half a marathon would simply be also half of that, that is:
0.7 x 10^5 feet
or
7 x 10^4 feet
=
