$Use:\\\\(a\cdot b)^n=a^n\cdot b^n\\\\a^n:a^m=a^{n-m}\\\\\left(a^n\right)^m=a^{n\cdot m}\\\\a^{-n}=\left(\frac{1}{a}\right)^{n}\\==================================\\\frac{(xy)^{-3}}{(x^{-5}y)^3}=\frac{x^{-3}y^{-3}}{(x^{-5})^3y^3}=\frac{x^{-3}y^{-3}}{x^{-15}y^3}=x^{-3-(-15)}y^{-3-3}=\boxed{x^{12}y^{-6}=\frac{x^{12}}{y^6}}$

Tony’s deposit earned $40.80 in simple over 3 years in an account with an interest rate of 1.7%. How much did Tony deposit?

Vsevolod [243]

Answer:

Tony's deposit was $800.

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=3\ years\\ I=\$40.80\\r=1.7\%=1.7/100=0.017$

substitute in the formula above

$40.80=P(0.017*3)$

$P=40.80/(0.017*3)$

$P=\$800$
