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:
-72
Step-by-step explanation:
Sum is adding so I just did substitution for this. 26+-72=-46 because a positive plus a negative equals a negative.
I'm not sure I understand the question. Is this worded correctly?
Answer:
<h2> 7.3%</h2>
Step-by-step explanation:
Using the formula for calculating the simple interest to get the rate of return;
Simple Interest = Principal * Rate * Time/100
Given Principal = $450,
Time (in years) = 1 year
Simple interest = $32.75
Rate (in %) =?
Substituting the given values in the given formula to get the rate;
32.75 = 450*1*R/100
450R = 3275
R = 3,275/450
R = 7.3%
The rate of return is 7.3%
