Answer:

y = $620.14 (nearest cent)

Explanation:

Given equation:


(4y)/(1.025^4)+y-2y(1.05)^2=\$1,500

Factor out y from the left side:


\implies y\left((4)/(1.025^4)+1-2(1.05)^2\right)=\$1,500

Carry out the arithmetic operations inside the parentheses by following the order of operations PEMDAS:

Calculate the exponents:


\implies y\left((4)/(1.103812891...)+1-2(1.1025)\right)=\$1,500

Carry out the multiplication and division from left to right:


\implies y\left(3.623802579...+1-2.205\right)=\$1,500

Carry out the addition and subtraction from left to right:


\implies y\left(4.623802579...-2.205\right)=\$1,500


\implies y\left(2.418802579...\right)=\$1,500

Finally, divide both sides by the coefficient of y to isolate y:


\implies (y\left(2.418802579...\right))/(2.418802579...)=(\$1,500)/(2.418802579...)


\implies y=\$620.141558...

Therefore, y = $620.14 (nearest cent)

Answer:

620.14

Explanation:

Original Equation:


(4y)/(1.025^4)+y-2y(1.05)^2=1500

Calculate exponents


(4y)/(1.103812890625)+y-2y(1.1025)=1500\\

Simplify:


3.6238025791990193084270042653997y + y - 2.205y = 1500

Add like terms


2.4188025791990193084270042653997y \approx 1500

Divide both sides by 7.012


y\approx 213.91
y\approx620.14
