The soda was $1.00.
Hot Dog- $3.50
Peanuts- $4.00
3.50+4.00= 7.50
Total paid is $11.50-$7.50= $4.00-$3.00(coupon)= $1.00
Using exponential function concepts, it is found that it represents a decay of 0.9%.
<h3>What is an exponential function?</h3>
A decaying exponential function is <em>modeled </em>by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function is:

Hence:


Thus, it represents a decay of 0.9%.
