Answer» In this kind of MATH, you do things in order and you will be all fine. First one is savings. Translate ENGLISH to math: "1/3 of Salary is savings" The English word "of" translates to "multiply" in math. the English word "is" translates to "equal". Therefore 1/3 * $4500 = "savings" So you know savings is $1500. Of that $1500, 50% is food. $1500 x 50% = "food" $1500 x 0.5 = $750 = "food" Of that $1500, 20% is rent. $1500 x 20% = "rent" $1500 x 0.2 = $300 = "rent" The amount spent for food and rent are $750 and $250 RESPECTIVELY.

Answer»

In this kind of MATH, you do things in order and you will be all fine.

First one is savings. Translate ENGLISH to math:

"1/3 of Salary is savings"

The English word "of" translates to "multiply" in math. the English word "is" translates to "equal". Therefore

1/3 * $4500 = "savings"

So you know savings is $1500.

Of that $1500, 50% is food.

$1500 x 50% = "food"

$1500 x 0.5 = $750 = "food"

Of that $1500, 20% is rent.

$1500 x 20% = "rent"

$1500 x 0.2 = $300 = "rent"

The amount spent for food and rent are $750 and $250 RESPECTIVELY.
