\(\frac{(15000+x)}{(15000+x+18000)}=0.55\)

Solve for x. You get \(x=7000\)

\(\frac{(15000+x)}{(15000+x+18000)}=0.55\)

Solve for x. You get \(x=7000\)

Why is that that Rebeca + jimmy's combined income is 15000 + X + 18000, shouldnt it be just 15k = 18k?

Rebecca's existing income is $15,000. Let Rebecca's new income be $(15,000+x).

This new income of $(15,000+x) constitues 55% of Rebecca and Jimmy's combined income.

Therefore Rebecca + Jimmy's income = Rebecca's new income + Jimmy's income = $(15,000+x) + $18,000

\(=> \frac{Rebecca'sNewIncome}{(Rebecca'sNewIncome + Jimmy'sIncome)}=55%\)

When Rebecca's income increases by x dollars, Rebecca and Jimmy's combined income also increases by x dollars. Does this make sense?

In my opinion, the question is a bit misleading. The answer assumes the reader is combining Rebecca's new income with Jimmy's current income. The way I read the question is Rebecca's current income + Jimmy's current income (which leads to an answer of $3,150).

Where is this from? From my perspective, this doesn't seem like a good question as there is ambiguity, although I may be missing something obvious.


Actually, there is no ambiguity in this question. It is extremely logical that the total salary will consist of Rebecca's new salary.

If Rebecca's new salary has to constitute 55% of their combined income, then obviously, their combined income includes her "new salary" only - there are no two ways about it.

I think a quick way to solve is to pick the middle answer and try:

c) 7000:
Total becca new = 7000+15000 = 22000
Total new all = 7000+15000+18000 = 40000

22000/40000 = 0,55 * 100 = 55%, Bazinga!

(22000/40000 = 220/400 --> /4 = 55/100= 55%)

NOTE: Now this is a first try lucky shot, if the answer was lower than 0,55 --> eliminate A,B,C --> try D or E

Let the increase in Rebecca's salary be $x
Rebecca's new income = $15000 + x

15000 + x = (55/100)* (15000 + x + 18000)
15000 + x = 0.55x + 18150
0.45x = 3150
x = $7000 Option C
