Question

The sales of a certain product after an initial release can be found by the equation s = 10 square root 5t + 15, where s represents the total sales (in thousands) and t represents the time in weeks after release. Make a table of values, graph the function and use the graph to estimate the sales 8 weeks after release.

a) S = 10/(5t) + 15
b) S = 5t10 + 15
c) S = 10t + 15
d) S = 15t + 10

Answer 1

The question involves creating a value table and graphing the function to estimate sales for a given time using a specific sales equation. By plotting different time values, we can estimate sales at 8 weeks either graphically or algebraically.

This correct answer a

Step-by-step explanation:

The student's question involves creating a table of values, graphing the function, and estimating sales 8 weeks after release, based on the provided equation for sales s with respect to time t in weeks.

To clarify any confusion, we should use the correctly stated sales equation s = 10√(5t) + 15. A table of values for this function is created by substituting various values of t into the equation and calculating the corresponding sales s.

After plotting these points on a graph, we can estimate the sales for time t = 8 weeks. However, an algebraic approach can also be utilized to provide a more accurate answer without relying on visual estimation from the graph.
