That isn’t right I don’t think, if a was 47 then it would be wayyyy bigger of a number. You are finding how 7a-2 is 47. First add 2 to both sides making it 7a=49
7 times what is 49?
That is a
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

Adds the numbers

-2.1-6x=1.5 add 2.1 to both sides
-6x=3.6 now divide both sides by -6
X= -.6
