Answer:
$21000
Step-by-step explanation:
This problem is on simple interest calcultion
A=P(1+r*n)
where
A=accumulated amount (final)
P= principal amount (initial), $15,000
r=interest written as decimal, 8% = 8/100= 0.08
n=number of years, 5years
Substituting into the expression we have
A=15000(1+0.08*5)
A= 15000(1+0.4)
A=15000(1.4)
A=$21000
Hence the ending balance that lucy would pay is $21000
