Answer 2

i think it 1,657.50

Answer 3

A=P(1+rt)

r is your interest rate
t is the time
P is the starting value I think

so

A=1500(1+1.5r)

7% is 0.07

A=1500(1+1.5(0.07))
A=1657.5
hence you are correct

Answer 4

Please show your work; it doesn't take long to do that.

the formula for simple interest is i=prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the number of years.

Please finish this: i = ( )( )( )

Answer 5

amorfide's approach is just fine.

In my approach we just add the interest to the principle to obtain the ending balance.

Answer 6

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year,
then, solving our equation

A = 1500(1 + (0.07 × 1.5)) = 1657.5
A = $ 1,657.50

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 1,500.00
at a rate of 7% per year
for 1.5 years is $ 1,657.50.
