Question 352790
Right off the bat you can tell that this answer is incorrect. In June, he sold 250 cars and in July he sold 14% <font color=red><u>fewer</u></font> cars. So the answer has to be smaller than 250.



So because "new" is smaller than "old", this means that the formula is actually



old amount-new amount/old amount=%/100



To make sure that the left side is a positive number.



So this means that the equation is {{{(250-x)/250=14/100}}}



I'll let you take it from here. You should get {{{x=215}}} as an answer (which is indeed smaller than 250).
