sergij07 [2.7K]

Given:

Number of gym members in last quarter = 490

Number of gym members in this quarter = 686

To find:

The percent of increase in the number of members.

Solution:

We have,

Number of gym members in last quarter = 490

Number of gym members in this quarter = 686

Now, the percent of increase in the number of members.

\%\text{ of increase}=\dfrac{{Members in this month - Members in last month}}{\text{Members in last month}}\times 100

\%\text{ of increase}=\dfrac{686-490}{490}\times 100

\%\text{ of increase}=\dfrac{196}{490}\times 100

\%\text{ of increase}=\dfrac{2}{5}\times 100

\%\text{ of increase}=2\times 20

\%\text{ of increase}=40

A. Original Price: $16.20
Tom [10]

Answer:

The final price is $ 22.68  And Proportional constant is 1.4  

Step-by-step explanation:

Given as :

The Original price = $ 16.20

The rate of increase = 40%

Let The final price = x

Now,

Final price after increase = initial price × ( 1 + \frac{\textrm Rate}{100}

Or. Final price after increase = $ 16.20 × ( 1 + \frac{\textrm 40}{100}

Or, Final price after increase = $ 16.20 × ( 1.4 )

∴ Final price after increase = $ 22.68

Now , Proportional constant = \frac{22.68}{16.20}

I.e Proportional constant = 1.4

Hence The final price is $ 22.68  And Proportional constant is 1.4  Answer
