Why are people still answering wrong on this? The answer was provided way early in the thread

Cost of Profit Car = x
Cost of Loss Car = y

x + .25x = 750 y -.25y = 750
1.25x = 750 .75y = 750
x= 600 y = 1000
$150 Profit $250 Loss

250-150 = $100 Loss

Aight well how come we can't get the answer by just taking 25% from 750 and so forth?

because 25% of 750 is not information you need.

you need to know what value would result in 750 after you take away 25%.

Same with the profit car, only that's easier. You are looking for the number that, after a 25% gain, would result in 750.

Hence the need for the algebra ...

A used car dealer complains to his friend that today has been a bad day. He has sold two cars, he tells his friend, for $750 each. One of the sales yielded him a 25% profit. On the other one he took a loss of 25%. "What are you worrying about?" asks his friend. "You had no loss whatsoever." "On the contrary, a substantial one," answered the dealer. Who is right?

car one cost him = 600
car two = 1000

car one plus car two cost him = 1600

he made 1500 for both cars.

the "substantial one" loss he took was the 1600 he paid minus the 1500 he made


yeah...it took me a minute to figure it out.



he paid 1600 for both cars but only made 1500 after the sales.
25% of x does not equal 25% of y....


i've made multiple corrections in this post but i think i have it nailed down now.




*final edit*

got it.
