Let Mary's income increase by x, then the equation will be 15,000 + x= (55/100)* (15,000 + x + 18000 ) 15,000 + x = (11/20) * (33,000 + x) 300,000 + 20x = 11x + 363,000 9 x = 63,000 x = 7,000 So, Answer will be C

Try the middle number: if Mary's annual income increase by $7,000, her income will be $22,000 and combined income will be 22,000 + 18,000 = $40,000. 55% of $40,000 is exactly $22,000.

Let X be the combined income. Since only Mary's income is increasing then John's income 18000 must constitute 45% of the total income , thus 18000 = 45% of X X = 18000*100/45 X= 40000

Thus increase in Mary's income is 40000 - (18000+15000) = 7000.

Should they mention to constitute 55% of Mary and John combined income after the increase? Cause for me it is not 100% clear. What do you guys think about the language?

Mary's annual income is $15000 and John's annual income is $18000. By how much Mary's annual income increase so that it constitutes 55% of Mary and John's combined income?

a. $3000 b. $4000 c. $7000 d. $8000 e. $9000

I am not sure where I am making the mistake. M= 15000 and J= 18000. Together M+J= 33,000. So J's income should increase to 55% of the combined which is 18,150. 18,150-15000 = 3150

Current ratio is \(\frac{15000}{33000} = \frac{15}{33}\) what should be added to denominator and numerator to make it \(\frac{55}{100}\) or \(\frac{11}{20}\) or \(\frac{22}{40}\) .

Adding 7 will make \(\frac{15+7}{33+7}\) = \(\frac{22}{40}\)

Answer 7000.
