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
Answer:
5x-6y-12=0
Step-by-step explanation:
...make y the subject y=-6/5x +2
...use the coefficient of x as the gradient,m=-6/5
...for a perpendicular line,find the negative reciprocal of the gradient,5/6
...sub into the eqn y= -1/m(x-a)+b
