Problema Solution
a game machine that costs $40 to make was on sale for an extra 25% off the original price, and it made a profit of no less than 20% of the cost. find the lowest original price
Answer provided by our tutors
Let original price=$x
20% Profit on $40 is 40+40*0.20= 40+8=48
So, x-x*(0.25)=48
x-0.25x=48
0.75x=48
x=48/(0.75)
x=64
So, Original price=$64
