Answer:
Let the number of cola bottles Ayesha bought be x. Cost of x cola bottles = *15x.
As per the problem she has bought 2x cans of orange juice at 25. Cost of 2x cans of orange juice = 50x.
As per the problem she has bought 2x-10 cans of lemonade at 20. Cost of 2x-10 cans of lemonade = *40x- 200.
Given total amount spent = 430.
Hence 15x + 50x + 40x - 200 = 430
=> 105x = 630
=> x = 6
So Ayesha bought 6 cola bottles, 12 orange juice cans and 2 lemonade cans.
