muminat
We are not given tables, so will just use the amortization formula.
P=\frac{A*((1+i)^n-1)}{i*(1+i)^n}
where 
P=amount to be deposited today, to be found
A=amount withdrawn each year=18000
i=Annual interest=9%
n=number of years = 20

Substituting values,
P=\frac{A*((1+i)^n-1)}{i*(1+i)^n}
=\frac{18000*((1+0.09)^{20}-1)}{0.09*(1+0.09)^{20}}

How much would a $3500 piano cost if it was on sale for 20% off with the 6% sales tax on the
Bess [88]

I'm not sure if you meant the tax was on the original proce or not, so here's both answers:

Tax on original price: $3010

Tax after sale: $2968

To get the amount off from the sale

3500x.2=700

3500-700=2800

To get the tax

(Tax on original price) 3500x.06=210

(Tax after sale) 2800x.06=168

Add tax onto price

(Tax on original price) 2800+210=3010

(Tax after sale) 2800+168=2968
