Answer:

Option A, n = ± 17

Step-by-step explanation:

<u>Step 1:  Add 29 to both sides</u>

n^2 - 29 = 260

n^2 - 29 + 29 = 260 + 29

n^2 = 289

<u>Step 2:  Square root both sides</u>

\sqrt{n^2} = \sqrt{289}

n = ± 17

Answer:  Option A, n = ± 17

babymother [125]

Answer:

Your question was a bit confusing so I found another related question. You can reference it with your own details.

A vendor bought 10 dozen eggs at the rate of Rs 22 per dozen. Six of the eggs were rotten. He sold the remaining eggs at the rate of Rs 2.50 per egg . Find his profit or loss

Vendor bought 10 dozen eggs which means the vendor bought:

= 10 * 12 eggs

= 120 eggs

6 were rotten and he sold the rest for Rs. 2.50 per egg.

= (120 - 6) * 2.5

= Rs. 285

The amount he spent on the eggs was:

= 10 dozen * 22

= Rs. 220

Profit = 285 - 220

= Rs. 65
