Thank you for the opportunity to help you with your question!

------------------------------------------------------------------------------------------------

1)

Let the number of female patients be x.

Number of male patients = 184



So, number of female patients = x = 138

------------------------------------------------------------------------------------------------

2)

Original price = $25

New price = $20


To find the percent decrease, subtract the lower price from the higher price and divide the difference by the

original price. To change the answer to a percent, you must multiply by 100.

 

Percent decrease in price


ANSWER: C) 20%
