Correct Answer

B. (W(t)=242-12t)

Step 1

Concept

The rate is \(\frac{122-218}{10-2}=-12\). From (218=a-12(2)), (a=242).

Step 2

Why this answer is correct

The correct answer is B. (W(t)=242-12t). The rate is \(\frac{122-218}{10-2}=-12\). From (218=a-12(2)), (a=242).

Step 3

Exam Tip

दर \(\frac{122-218}{10-2}=-12\) है। (218=a-12(2)) से (a=242) मिलता है।
