Answer:1/25
Step-by-step explanation: do 5 to the second power which will get all combinations then do 1 as the numerator over the denominator which is the number of combinations.
20% off means it is selling for 80% of the original price ( 100% - 20% =80%)
Divide the sale price by 80% as a decimal:
380/0.80 = 475
The original price was $475
Justify:
Multiply the original price by 20% and subtract:
475 x 0.20 = 95
475-95 = $380 which is the sale price.
If you divide 21/49 by 7 you get 3/7
