What is the mode of 82 , 79 , 72 , 72 , 81 , 77 , 69

72

Step-by-step explanation:

In mathematics,we will have to understand the following terms before solving the given question

Mode means the highest frequency

Mean means sum of the numbers divided by the number

Median means the middle number

But we are to determine the mode from this question,

The mode will be 72 because it appears twice in the question

$ 2,508

Step-by-step explanation:

Given,

In rent,

Amount deposited = $ 1,500

Time, t = 4 years,

Monthly payment = $ 865 ⇒ Total payment (in 4 years) = 865 × 12 × 4 = $ 41520

Thus, the total amount she will pay in rent,

= Amount deposited + Total payment she did

= $ 1500 + $ 41520

= $ 43,020

Now, in buying,

Monthly payment = $ 844 ⇒ Total payment(in 4 years) = 844 × 12 × 4 = $ 40512

Let the closing costs in buying be x,

Thus, the total amount she will pay in rent,

= Closing cost + Total payment she did

= $ ( x + 40512 ),

In order for the cost to buy to be the same as the cost to rent,

Hence, the closing cost is $ 2,508.
