During the first hour of operation the farm stand owner sold 15% of the apples he had. On the second hour he sold 20% of the rem
Gnesinka [82]

Answer:

22.95 kg

Step-by-step explanation:

Let's say the farm stand owner starts with x kg of apples.

During the first hour, he sells 15% of the apples:

0.15 x

This means he's left with 85% of the original apples.  During the second hour, he sells 20% of the remaining apples:

0.20 (0.85 x)

= 0.17 x

He's sold a total of 15% + 17% = 32% of the apples, so he's left with 68% of the apples.  Continuing the pattern, the apples sold during the third hour:

0.25 (0.68 x)

= 0.17 x

He's sold 49% of the apples and is left with 51%.  The apples sold during the fourth hour:

0.30 (0.51 x)

= 0.153 x

If 0.17 x = 25.5, then x = 150.  So the apples sold during the fourth hour is:

0.153 (150) = 22.95
