Answer:
Step-by-step explanation:
we know that
In this problem we have a exponential function of the form
where
a is the initial value or y-intercept
b is the base of the exponential function
r is the rate in decimal form
b=(1+r)
In this problem we have
x ----> the number of days
y ----> the number of shoppers
a=120
r=10%=10/100=0.10
b=1+0.10=1.10
substitute the values
First day
Second day
For x=1 day
substitute the value of x in the equation and solve for y
Third day
For x=2 days
Fourth day
For x=3 days
Fifth day
For x=4 days
Sixth day
For x=5 days
Seventh day
For x=6 days
