kotegsom [21]

Answer:

89

Step-by-step explanation:

25 watches equals a $50 bonus + 25 * 4

25*4=100

100+50=150

150 can go into 506 three times with a remainder of 56.

since it fits three times that is 75 watches

now divided the remainder by 4 and add this to 75.

56/4=14

75+14=89

89 watches

2^x = 2^20 / 2

2^x = 2^19

On the 19th day, Lily was half.
