I have sometimes trouble understanding the question right. And the following problem is one of those: (But I really think the Answer is wrong):
An appliance store sells two size air conditioners, an 8000 BTU air conditioner for $235 and an 14000 BTU air conditioner for $465. If, during a certain sale, the store sold 3 more of the 8000 BTU models than 14000 BTU models and generated revenues of $3495, hot many air conditioners did it sell?
A. 3
B. 6
C. 9
D. 12
E. 13
So the CAT says that the answer should be C based on the following equation: 235x + 465(x + 3) = 3495 --> x = 3 --> 2x + 3 --> 9
How is that so cause, based on the questions i would write the equation:
235(x + 3) + 465(x) = 3495
(BTW: I made sure the question is copied as in the original!)
whats going on ?
