B) 19
C) 20
D) 21

Answer 1

The mobile phone company plans to increase its production each week by 20 phones. The value of N is 21.

Step-by-step explanation:

The mobile phone company in Dubai plans to increase its production each week by 20 phones. Starting from 200 phones in week 1, the company will produce 220 phones in week 2, 240 phones in week 3, and so on, until it reaches 600 phones in week N. We need to find the value of N. To do this, we can set up an equation:

200 + 20(N-1) = 600

Simplifying the equation:

20(N-1) = 400

N-1 = 20

N = 21

Therefore, the value of N is 21. So, the correct answer is D) 21.
