Answer:
21. y = 75000·0.935^t
22. after 74.6 days
23. y = 27.8112·1.18832^t
24. 18.8% per month
25. 1748
Step-by-step explanation:
22. It is convenient to use the graphing calculator to solve this problem. The number of days is where the exponential curve has the value 500. It is about 74.55 days. (see the first attachment)
__
23. y = 27.8112·1.18832^t (see the second attachment)
__
24. The rate of change is the difference between the base of the exponential and 1, often expressed as a percentage. The time period is the units of t.
(1.18832 -1) × 100% ≈ 18.8% . . . . per month
__
25. Evaluating the function for t=24 gives y ≈ 1748.30425259 ≈ 1748.

<em>Comment on graphing calculator</em>
A graphing calculator can make very short work of problems like these. It is worthwhile to get to know how to use one well.
The error in the given equation is that the product of 24 and x is equal to 8
while the original product according to sentence is of 8 and x which is equal to 24
Step-by-step explanation:
we will convert the given sentence into equation to compare it with the given equation.
Let x be the number
Then
"8 multiplied by a number x."
"24 is 8 multiplied by a number x."
24 is a product of 8 and x so
The error in the given equation is that the product of 24 and x is equal to 8
while the original product according to sentence is of 8 and x which is equal to 24
