Final answer:
To find the value of a in the equation D.Y = 21.94 × 1.02 × a, divide both sides of the equation by 21.94 × 1.02 to isolate a. The value of a is 1.0026.
Step-by-step explanation:
To solve the equation D.Y = 21.94 × 1.02 × a, we need to divide both sides of the equation by 21.94 × 1.02 to isolate the variable a. This gives us:
a = D.Y / (21.94 × 1.02)
Substituting the given value for D.Y in the equation, we have:
a = 21.9488 / (21.94 × 1.02)
Simplifying the expression, we get:
a = 1.0026
Therefore, the answer is: (c) 1.0026
