Answer:
720 apples
Step-by-step explanation:
Let A be the number of apples in the small pack.
QTY for Small Cartons is 15A,
QTY for Big Cartons is 20(A+15) = 20A+300
From small cartons makes 25% or 1/4 of total, means the big carton makes 75% of total, or 3/4 of total. This also means the qty in big carton is 3 times of small carton
20A+300 = 3X (15A)= 45A
300 = 25A
A=12
Altogether = 15A+(20A+300) = 720 Apples
X miles per hour - <span> speed of the boat in still water
(x - 2) - speed up the river
(x + 2) - speed down the river
</span>

=

30 * (x + 2) = 38 * (x - 2)
30x + 60 = 38x - 76
- 8x = - 136
x =
17 miles per hour - <span>
the speed of the boat in still water.</span>
