We can find the sales tax for the pool by multiplying the sale price and the sales tax rate.

$525*0.07=36.75$

So the sales tax is $36.75

Answer:

$3,273.14

Step-by-step explanation:

-We first calculate the effective interest rate of 1.13% compounded daily:

$i_m=(1+i/m)^m-1\\\\=(1+0.0113/365)^{365}-1\\\\=0.011363909$

#Now, we calculate the compounded amount after 2 years using this rate:

$A=P(1+i)^n\\\\=3200(1.011363909)^2\\\\\\=3273.14$

Hence, the compounded amount after 2 years is $3,273.14
