Answer:
28.44$
Step-by-step explanation:
The original price of a shirt is A.
This shirt is on sale for 25% => the price of that shirt after being sale:
P1 = A - A x 25% = A - A x (25/100) = A - A x (1/4) = A x (3/4)
This shirt is discounted one more time for 25% => the price of that shirt after being discounted second time.
P2 = P1 - P1 x 25% = P1 - P1 x (25/100) = P1 - P1 x (1/4) = P1 x (3/4) = A x (3/4)^2
P2 is given to be equal to 16$, then there is an expression:
P2 = 16
or
A x (3/4)^2 = 16
=> A x (9/16) = 16
=> A = 16 x (16/9) = 28.44$
Hope this helps!

Step-by-step explanation: in total the journey is 105mins so if she has to reach by 9:30. Then she has to leave her house 105mins before 9:30
Step-by-step explanation:
![\frac{140}{130} = 1.07692308 \approx \: 1.08 \\ \\ 104\% = \frac{104}{100} = 1.04 \\ \\ \because \: 1.08 > 1.04 \\ \\ \therefore \: \frac{140}{130} > 104\% \\](https://tex.z-dn.net/?f=%20%5Cfrac%7B140%7D%7B130%7D%20%20%3D%201.07692308%20%5Capprox%20%5C%3A%201.08%20%5C%5C%20%20%5C%5C%20%20104%5C%25%20%3D%20%5Cfrac%7B104%7D%7B100%7D%20%20%3D%201.04%20%5C%5C%20%20%5C%5C%20%20%5Cbecause%20%5C%3A%201.08%20%3E%201.04%20%5C%5C%20%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%20%20%5Cfrac%7B140%7D%7B130%7D%20%20%3E%20104%5C%25%20%20%5C%5C%20)
