the answer is B
2A=75+B
A=75+B/2
we have that A+B=900

75+B/2+B=900

B=575

A=900-575=325

A. $275
B. $325
C. $425
D. $575
E. $625

Given

2A-75 = B--1
A+B =900--2

Substituting value of B from 2 in 1

--> A = 325
hence B

MAGOOSH OFFICIAL SOLUTION:

This is a relatively easy word problem. Let A be Alice’s share, and B, Bruce’s share. Clearly A + B = 900. We also are told that 2A = B + 75. To solve, use substitution. Solve this for B:
B = 2A – 75.

Now, plug this into the first equation:
A + (2A – 75) = 900
3A = 900 + 75
A = 300 + 25 = $325

Alice’s share is $325.

Answer = (B).

Answer = B = 325

Alice ................ Bruce ................... Total

x ....................... 900-x ...................... 900

Setting up the equation for Alice

2x = (900-x) + 75

3x = 900 + 75

x = 325

Kudos for a correct solution.


Let Alice's payment = A

Let Bruce's payment = B

A + B =900..............1

2A = B + 75.............2

From equation 1: B = 900 - A

Substitute in 2

2A = 900 - A + 75

3A = 975.................No Need to perform any calculations. If it is 900 then A = 300, so we need number little bit higher 300

Answer: B

We can let a = the amount Alice paid for her refrigerator and b = the amount Bruce paid for his refrigerator. Therefore,

a + b = 900

and

2a = b + 75

Isolating b in the second equation, we have b = 2a - 75. Substituting this for b in the first equation, we have:

a + 2a - 75 = 900

3a = 975

a = 325

Answer: B

Hi All,

We're told that Alice and Bruce each bought a refrigerator, and the sum of their purchases was $900. We're also told that TWICE of what Alice paid was $75 MORE than what Bruce paid. We're asked what did Alice paid for her refrigerator. This question can be solved in a couple of different ways, including by TESTing THE ANSWERS.

To start, as an estimate, if Bruce paid exactly twice what Alice paid, then their two purchase prices would have been 600 and 300, respectively. However, we know that that did NOT happen (since "twice what Alice paid was $75 MORE than what Bruce paid"). Thus, Alice would have paid a bit more than $300. Let's TEST Answer B first...

Answer B: $325
IF.... Alice paid $325, then
Bruce paid 2($325) - $75 = $650 - $75 = $575
Total paid by both = $325 + $575 = $900
This is an exact match for what we were told, so this MUST be the answer.

Final Answer:

GMAT assassins aren't born, they're made,
Rich
