Answer:
1138
Step-by-step explanation:
From the information given:
We can represent it perfectly in an exponential form:

where;
p = initial value = 120
q = base of the exponential form
q = 1 + r
here; r = rate in decimal = 10% = 0.1
Then q can now be = 1 + 0.1 = 1.1
Replacing it into the exponential form, we get:

where;
x = number of days and m = number of shoppers
Thus:
For the first day:

m = 120
For the second day:

m = 132
For the third day:

m = 145.2
For the fourth day

m = 159.72
For the fifth-day

m = 175.692
For the sixth-day

m = 193.2612
For the seventh-day

m = 212.58732
Thus; the total numbers of shoppers for the first 7 days is:

= 1138.46052
≅ 1138
Answer:
<em>a) 15 b) 6 c) -3</em>
Step-by-step explanation:
x - y = 3
a) 5 (x - y) = 5 (3) = 15
b) 2x - 2y = 2 (x - y) = 2 (3) = 6
c) y - x = -1 (x - y) = -1 (3) = -3
