First a divided 78524.60 by 4 which got me 19631.15. I multiplied 19631.15 and got 58893.45. After that I then multiplied 78524.60 by 2 on a separate problem, I got 157049.20. Then you add 58893.45+ 157049.20 and you get 215942.65.

Further explanation

Order of Operations in Mathematics follow this following rule :

  • Parentheses
  • Exponents
  • Multiplication and Division
  • Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem!

Sal bought a house for $78,524.60

[tex]\texttt{Initial Price of Sal's House} = \boxed {\$ 78,524.60}[/tex]

Twelve years later he sold the house for 2³/₄ times as much.

[tex]\texttt{Sale Price of Sal's House} = 2\frac{3}{4} \times \texttt{Initial Price of Sal's House}[/tex]

[tex]\texttt{Sale Price of Sal's House} = 2\frac{3}{4} \times \$ 78,524.60[/tex]

[tex]\texttt{Sale Price of Sal's House} = ( 2 + \frac{3}{4} ) \times \$ 78,524.60[/tex]

[tex]\texttt{Sale Price of Sal's House} = ( 2 \times \$ 78,524.60 ) + ( \frac{3}{4} \times \$ 78,524.60 )[/tex]

[tex]\texttt{Sale Price of Sal's House} = ( \$ 157,049.2 ) + ( \$ 58,893.45 )[/tex]

[tex]\texttt{Sale Price of Sal's House} = \boxed {\$ 215,942.65}[/tex]
