Question

an office worker earns R6400 per month. his monthly expenses are 1/5 for rent , 2/7 for car payment, 1/6 for insurance, 1/3 for other monthly living expenses and the rest he deposits into a savings account. how much does he save per month?

Answer 1

The officer saves $91.45 per month

~Step-by-step explanation~

Ok this is how I do fractions and its not very good, but it works.

First I divided 6400 by 5, 6, and 7, (I didn't do 3 because you can just multiply the answer to 6 by 2.) the reason I divided these is to see how much 1 part of their fraction is worth. So in total I got 1066.66 (irrational number) for insurance which means I got 2133.32 for his monthly living ( had to multiply by 2). For his car payment I got 1828.57 (I divided and then multiplied by 2) and for his rent I got 1280. I added these all together to get the total he spends each month which was 6308.55, and I subtracted that from 6400 to figure out that he puts $91.45 in his savings account

Answer 2

The answer is R91.43.

Explanation:

Monthly salary of the worker = R6400

The monthly expenses are 1/5 for rent that is
`(1)/(5)*6400= 1280`

The car payment is 2/7 that is
`(2)/(7)*6400= 1828.57`

The insurance is 1/6 that is
`(1)/(6)*6400= 1066.67`

Few other monthly living expenses are 1/3 that is
`(1)/(3)*6400= 2133.33`

We will total these values:

`1280+1828.57+1066.67+2133.33=6308.57`

So, the amount that is saved per month =
`6400-6308.57=91.43`

The answer is R91.43.
