Problema Solution
An item that costs $80 to make was marked down 20% from the original price, and it made a profit of no less than 15% of the cost. Find the lowest original price.
Answer provided by our tutors
Let original price=$x
15% Profit on $80 is 80+80*0.15= 80+12=92
So, x-x*(0.20)=92
x-0.2x=92
0.8x=92
x=92/(0.8)
x=115
So, Original price=$115
