Question

Which situation could be modeled by the function y = 400(1 – 0.17)x?

Answer 1

Looking at the equation, this could model a situation in linear decay rate process. The variable y represents the amount left after time x. The original amount is 400 units. Then, the decay rate is 17%. It is called linear because the time is multiplied to the rate, not an exponent which would now make it exponential decay rate. 

Answer 2

Answer:

A model of the profit that a company makes for a certain number of a given product.

Step-by-step explanation:

Imagine that you have to calculate the amount of money that you will earn in profit by selling a certain amount of products that are sold at 400 dollars, and you need 17% of that amount to cover for expenses, or production costs, so the formula would be y=400(1-017)x that would represent the amount of money earned in profit.
