A girl entered a store and bought x flowers for y dollars (x and y are integers). When she was about to leave, the clerk said, "If you buy 10 more flowers I will give you all for $ 2, and you will save 80 cents a dozen". The values of x and y are:
A(15,1)
B(10,1)
C(5,1)
DCannot be determined
Answer: Option (Login/Signup)
Show Explanation
Given she bought x flowers for y dollars.
So 1 flower cost = yx
12 flowers or 1 dozen cost = 12yx
Again, x+10 cost = 2 dollars
1 flower cost = 210+x
12 flowers or 1 dozen cost = 2*1210+x=2410+x
Given that this new dozen cost is 80 cents or 4/5 dollar less than original cost.
=>12yx−2410+x = 45
