Answer:
Account A: Decreasing at 8 % per year
Account B: Decreasing at 10.00 % per year
Account B shows the greater percentage change
Step-by-step explanation:
Part A: Percent change from exponential formula
f(x) = 9628(0.92)ˣ
The general formula for an exponential function is
y = ab^x, where
b = the base of the exponential function.
if b < 1, we have an exponential decay function.
ƒ(x) decreases as x increases.
Account A is decreasing each year.
We can rewrite the formula for an exponential decay function as:
y = a(1 – b)ˣ, where
1 – b = the decay factor
b = the percent change in decimal form
If we compare the two formulas, we find
0.92 = 1 - b
b = 1 - 0.92 = 0.08 = 8 %
The account is decreasing at an annual rate of 8 %.The account is decreasing at an annual rate of 10.00 %.
Account B recorded a greater percentage change in the amount of money over the previous year.
The only way to do that is with +7 and -7 .
Given that the amount of fiber in 100 grams of beans is 3.6 grams the amount of fiber consumed from 
of the small tin is <u>4.8 grams</u>.
<h3>How can the amount of fiber consumed be calculated?</h3>
From the given table, we have;
Mass of fiber in 100 g of beans = 3.6 grams
Mass of beans in the small tin = 200 grams
The quantity of the beans eaten = 
of the small tin
Required:
The amount of fiber to consumed from eating of the small tin
Solution;
Therefore;
The amount of fiber consumed by eating of the small tin = <u>4.8 grams</u>

25% of something is 5000000, so total is 4*5000000 = 20 million
Let us take 0instead of 2.2 meaning 8.5-2.2=6.3
then we need to find the mid of 6.3=3.15
then we need to add 2.2 to 3.15= 5.35
