The total price of a basic computer and printer are $2,500. If the same printer had been purchased with an enhanced computer whose price was $500 more than the price of the basic computer, then the price of the printer would have been 1/5 of that total. What was the price of the basic computer? A. 1500 B. 1600 C. 1750 D. 1900 E. 2000 I started doing this question, but got stuck. Let x be the price of the basic computer and y be the price of the printer. x + y = 2500 (1) Price of the enhanced computer = x + 500 (2) Price of the printer i.e. y = 1/5 (x+500) (3) Solving 1 and 2 will give me x = 2000. But the answer is not correct, its D?

A) 1500
B) 1600
C) 1750
D) 1900
E) 2000
I started doing this question, but got stuck.
Let x be the price of the basic computer and y be the price of the printer.
x + y = 2500 (1)
Price of the enhanced computer = x + 500 (2)
Price of the printer i.e. y = 1/5 (x+500) (3)
Solving 1 and 2 will give me x = 2000. But the answer is not correct, its D? My try: Here you have: c=computer p=price Total price of the combo 1: c+p=2500 Total price of the combo 2: c+p+500 = 3000 (here you are not changing any price, only adding 500) p=3000/5=600 Then: C+600 = 2500 C=1900

Now, we are told that the price of the printer is 1/5 of that new total price: P=1/5*$3,000=$600. Plug this value in the first equation: C+600=$2,500 > C=$1,900. Answer: D.

Let B, and P be price of basic computer and printer resp. given B+P=2500
also advanced computer price = B+500 and P= 1/5(2500 + 500) = 600 Substituting this value in the first equation we get
B = 2500 600 = 1900 hence D.

p +c=2500 p+c+2500=total(T) Hence T= 3000 P= 1/5*3000=600 HENCE c=1900

Did using one variable: Price of basic computer = x Price of printer = (2500  x) Price of enhanced computer = x + 500 Setting up the equation \(2500  x = \frac{1}{5} * (x+500+2500x)\) x = 1900 = Answer = D

Let the price of basic computer be C and the price of the printer be P: C+P=$2,500.
The price of the enhanced computer will be C+500 and total price for that computer and the printer will be 2,500+500=$3,000. Now, we are told that the price of the printer is 1/5 of that new total price: P=1/5*$3,000=$600.
Plug this value in the first equation: C+600=$2,500 > C=$1,900.
Answer: D.

OK, I saw that answer, but I am sorry if I am missunderstanding, it might be because I am not an English nativespeaker. The question says : The total price of a basic computer and printer are $2,500. >> Total price = CB + P = $2,500. Ok ...If the same printer had been purchased with an enhanced computer whose price was $500 more than the price of the basic computer, >> CE = CB+ 500, hence New Total Price = (CB + 500) + P. Here, from what I undestand, it doesn't say that the new total price is $500 more, just the isolated Computer Enhanced. ...,then the price of the printer would have been 1/5 of that total. >> And here it says that THE PRICE OF THE PRINTER, only the printer, is 1/5 of THAT TOTAL. So I was doing P = 1/5*2,500. I am confused with the wording I think...

What was the price of the basic computer?
A. 1500 B. 1600 C. 1750 D. 1900 E. 2000 We are given that the total price of a basic computer and a printer was $2,500. If we let a = the price of the basic computer and b = the price of the printer, we can create the following equation: a + b = 2,500 We are next given that if the same printer had been purchased with an enhanced computer whose price was $500 more than the price of the basic computer, then the price of the printer would have been 1/5 of that total. If we let the price of the enhanced computer = 500 + a, then we can create the following equation: (1/5)(500 + a + b) = b Since a + b = 2,500, we can substitute 2,500 for a + b into the equation (1/5)(500 + a + b) = b. (1/5)(500 + 2,500) = b (1/5)(3,000) = b 600 = b Since b = 600 and a + b = 2,500, we can determine the value of a. a + 600 = 2,500 a = 1,900 Alternate Solution The package price of the enhanced computer + printer is $3000. Onefifth of that total is $600, which is the price of the printer by itself. Since the package price of the basic computer + printer is $2,500, we subtract the printer price of $600, getting $1,900 as the price of the basic computer only. Answer: D
