Sal bought a house for $78,524.60. Twelve years later he sold the house for 2 3/4 times as much. What was the sale price of the house?

Answers

Answer 1
Answer:

The sale price of the house was $ 215,942.65

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

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

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

\texttt{Sale Price of Sal's House} = 2(3)/(4) * \texttt{Initial Price of Sal's House}

\texttt{Sale Price of Sal's House} = 2(3)/(4) * \$ 78,524.60

\texttt{Sale Price of Sal's House} = ( 2 + (3)/(4) ) * \$ 78,524.60

\texttt{Sale Price of Sal's House} = ( 2 * \$ 78,524.60 ) + ( (3)/(4) * \$ 78,524.60 )

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

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

Answer 2
Answer: 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.

                                                    Question # 4

Answer:

Total number of cameras left to bid on = 3/5

Step-by-step Explanation:

To determine:

What fraction of the total number of cameras is left to bid on?

Solution Steps:

  • Total number of antique cameras contributed by a local shop = 10
  • The number of cameras accepted for bids = 4

Total number of cameras left to bid on = 10/10 - 4/10

                                                                  = 6/10

                                                                   = 3/5   ∵ As 6/10 = 3/5

Hence, total number of cameras left to bid on = 3/5

                                               Question # 5

Answer:

The remaining portion of tickets = 17/100

Step-by-step Explanation:

To determine:

What portion of the tickets remain?

Solution Steps:

  • The total number of tickets = 100
  • The number of tickets that were sold in first week = 83

The remaining portion of tickets = 100/100 - 83/100

                                                       = 17/100

Hence, the remaining portion of tickets = 17/100

If 5 miles = 8km. how many km in 250 miles?

Answers

250 miles is equivalent to 400 kilometers.

We have,

To find out how many kilometers are equivalent to 250 miles, we can set up a proportion using the given information that 5 miles are equal to 8 kilometers.

5 miles : 8 kilometers

We can set up the proportion:

5 miles / 8 kilometers = 250 miles / x kilometers

To solve for x (the number of kilometers in 250 miles), we can cross-multiply and then divide:

5 miles x (x kilometers) = 8 kilometers x 250 miles

5x = 2000

Dividing both sides by 5:

x = 400

Therefore,

250 miles is equivalent to 400 kilometers.
