Correct Answer

B. (W(t)=222-12t)

Step 1

Concept

The rate is \(\frac{114-186}{9-3}=-12\). From (186=a-12(3)), (a=222).

Step 2

Why this answer is correct

The correct answer is B. (W(t)=222-12t). The rate is \(\frac{114-186}{9-3}=-12\). From (186=a-12(3)), (a=222).

Step 3

Exam Tip

दर \(\frac{114-186}{9-3}=-12\) है। (186=a-12(3)) से (a=222) मिलता है।
