The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is stu
Mashcka [7]

The account that recorded a greater percentage change in amount of money over the previous year is year 4

<h3>Part A: Is the amount of money in account A increasing or decreasing?</h3>

The exponential function is given as:

f(x) = 9628 * (0.92)^x

An exponential function is represented as:

f(x) = ab^x

If b is less than 0, then the function is an increasing function.

So, the function f(x) = 9628 * (0.92)^x is a decreasing function.

The percentage of decrement is then calculated as:

r =1 - b

This gives

r = 1 - 0.92

Evaluate

r = 0.08

Express as percentage

r = 8%

Hence, the percentage of decrement is 8%

<h3>Part B: The account that recorded a greater percentage change in amount of money over the previous year</h3>

r  1 2 3 4

g(r) 8,972 8,074.80 7,267.32 6,540.59

As a general rule:

As the number of years increases, the percentage change increases

Hence, the account that recorded a greater percentage change in amount of money over the previous year is year 4

Mrs. Cerra planted 4 ⅞ acres of wheat and 1 ⅝ acres of corn. How much more wheat did she plant than corn?
alukav5142 [94]
We can subtract the acres of corn from the acres of wheat.
4 \frac{7}{8} - 1  \frac{5}{8} = 3 \frac{2}{8} = 3  \frac{1}{4}
She planted 3 1/4 more acres of wheat than corn.
