a business finds that their ratio of spending to income is 5 to 9 . their total profit is $ 48000 . what is their total income ?
Select the correct option
A) $ 90000	B) $ 108000	C) $ 119000	D) $ 126000	E) $ 140000

Rationale: let x equal the amount of spending , and y equal the amount of income . we know that x = 5 / 9 y we also know that x = y - 48000 therefore we can simplify to : y - 48000 = 5 / 9 y we isolate y , and get : 4 / 9 y = 48000 and to solve for y , we get : y = 48000 answer : b
Answer: B
