Step 1

Let ‘x’ denotes the amount of aspirin in bloodstream after ‘t’ hrs. The exponential model which describes the given situation where ‘A’ is the amount of aspirin at start and ‘k’ is the rate of growth/decay.

Step 2

Using the values given, calculate the rate ‘k’ to formulate the specific model.

Step 3

‘k’ can be calculated more specifically if we apply...
