Actually Welcome to the Concept of the Average rate of change.

The average rate of change can be calculated by, finding the change of the two readings and getting a average between them.

here, for x =3 to x =5

1.) in the interval, x =3 to x = 4

the change is ==> 287 - 125 = 162

2.) in the interval, x = 4 to x=5

the change is ==> 549-287 = 262

Now the average ==> 162+262/2 ===> 212

Hence the average rate of change is 212

The cost of a jacket increased from $90.00 to $103.50. What is the percentage increase of the cost of the jacket?

a_sh-v [17]

Answer:

So the Percentage Increase = 15 %

Step-by-step explanation:

Given:

Original price = $ 90.00

New Price = $103.50

To Find:

Percentage Increase = ?

Solution:

Percentage Increase $=\frac{Difference in Value* 100}{Original value}$ %

Now In our Given Data

Difference in Value = New Value - Original Price

Putting in the values

Difference in Value = 103.50 - 90.00

= $13.50

Now we Know all the value and the formula is

Percentage Increase $=\frac{Difference in Value* 100}{Original value}$ %

Putting in the values

Percentage Increase $=\frac{13.50* 100}{90.00}$ %

$=\frac{1350}{90.00}$ %

= 15%

which tells us that

Percentage Increase = 15 %

The table shows the number of toys sold at Penelope's Toys and Games store in different years. Find the rate of change in the nu

Aliun [14]

Answer:

Year - (1993 - 1995)

Step-by-step explanation:

Rate of change in the number of toys sold = $\frac{\text{change in number of toys sold}}{\text{Time interval}}$

In the interval (1990 - 1993),

Rate of change in number of toys sold = $\frac{32000-20000}{1993-1990}$

= $\frac{12000}{3}$

= 4000

In the interval (1993 - 1995),

Rate of change = $\frac{42000-32000}{1995-1993}$

= $\frac{10000}{2}$

= 5000

In the interval (2000 - 1995),

Rate of change = $\frac{57000-42000}{2000-1995}$

= $\frac{15000}{5}$

= 3000

In the interval (2006 - 2000),

Rate of change = $\frac{63000-57000}{2006-2000}$

= $\frac{6000}{6}$

= 1000

Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).
