The exponential function used to represent the profit after t years is
<h3>Exponential function</h3>
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y, and b is the multiplier.
Let y represent the profit after t years.
Since the profit on a given day is $550 and is growing exponentially at a rate of 60% per year. Hence:
- a = 550
- b = 100% + 50% = 1.6
The profit function is given by:

The percentage discount given on the prove is not supplied ; Assume the percentage discount given on the phone is 60%
Answer:
0.4d
d - 0.6d
Step-by-step explanation:
Given that :
Percentage Discount given on phone = 60%
The discounted pice :
Initial percentage = 100%
Discount percentage = 60%
(100% - 60%) of price
(100% - 60%) * d
40%*d
0.4d
Also ;
(100% - 60%) * d
100%*d - 60%d
d - 0.6d
The amount in the account after the daily deposit for 5 days is $5
<h3>How to determine the amount in the account?</h3>
The given parameters i the question are represented as follows
Initial balance = -$30
Daily deposit = $7
Number of days of deposit = 5
The equation that represents the amount in the account is represented as
Amount = Initial balance + Daily deposit * Number of days
Substitute the known values in the above equation So, we have the following equation
Amount = -30 + 7 * 5
Evaluate
Amount = 5
Hence, the amount is $5
