- R represents the amount, in billions of dollars, of retail sales for the

Answer 1

The amount in billions of dollars of retail sales in the year 2000 was $263.3 billion, as per the model R(t)=263.3+11.6t with t=0.

Step-by-step explanation:

The question asks to determine the amount in billions of dollars of retail sales in the year 2000 based on the provided model R(t)=263.3+11.6t, where t represents the number of years since 2000, and R represents the amount in billions of dollars of retail sales.

To find the retail sales for the year 2000, substitute t with 0, since the year 2000 is the reference point (i.e., t = 0 for the year 2000).

Step 1: Substitute t = 0 into the model:

R(0) = 263.3 + 11.6(0)

R(0) = 263.3 + 0

Step 2: Simplify the equation:

R(0) = 263.3

Therefore, the amount in billions of dollars of retail sales in the year 2000 was $263.3 billion.
