The owner of a health club decides to reduce the $35 membership fee by $5. What is the approximate percent decrease in the fee?

Question

The percent decrease is approximately 0.14%.
The percent decrease is approximately 0.85%.
The percent decrease is approximately 14%.
The percent decrease is approximately 85%.

Answer 1

To calculate the percent decrease in the membership fee, you can use the formula for percent change:

\[ \text{Percent Decrease} = \left(\frac{\text{Original Price} - \text{New Price}}{\text{Original Price}}\right) \times 100 \]

In this case:

• Original Price = $35
• New Price = $35 - $5 = $30

Now plug these values into the formula:

\[ \text{Percent Decrease} = \left(\frac{35 - 30}{35}\right) \times 100 \]

\[ = \left(\frac{5}{35}\right) \times 100 \]

\[ = \left(\frac{1}{7}\right) \times 100 \approx 14.29% \]

Rounding to the nearest whole number, the percent decrease is approximately 14%.

So the correct answer is: The percent decrease is approximately 14%.
