Percentage?

Question

A family spends 20% of its monthly income on food, 23% on rent, and 42% on other expenses and saves the balance. If the family saves $360 per month, what is its monthly income?

Answer 1

20+23+42=85
100-85=15

15% is saved

360/0.15=2400

$2,400.00 is the monthly income.

Answer 2

100 % - (20% + 23% + 42%) = 100% - 85% = 15% is saved

and if the 15% of the income is 360$, then the income will be

360$ X 100$ / 15% = 2400$ a month

Answer 3

Let us see the percentage of savings.

100 - (20 + 23 + 42) = 100 - 85 = 15% is saved

If 15% of income is 360, the income will be

360 X 100 / 15 = 2400 dollars a month

Answer 4

20+23+42=85

85 percent of their income is spend on monthly necessities.

15 percent is saved monthly.

$360 is 15 percent of their monthly income.

360/.15 = $2400

their monthly income is 2400 dollars.

Answer 5

x- (20%+23%+42%)x, x being monthly income=360(balance)

x- 85/100*x=360
15/100x=360
x=360*100/15
x=2400

2400 is the monthly income.

Answer 6

100% - 20% - 23% -42% = 15%

$360 is 15% of their monthy income.

360/x = 15/100
360/(15/100) = x
2400 = x

Therefore, their monthy income is $2400.

Answer 7

let x be the number of monthly income. At the end of the month, the family saves $360. That means the total monthly income minus the the amount of money they spend equals 360

x - (.2x + .23x + .42x) = 360

x - .2x - .23x - .42x = 360
.15x = 360
x = $2,400 / month

Answer 8

if "m" is their amount of monthy income, then m minus all of their expenses is equal to what they have left over, $360:

m - 0.2m - 0.23m - 0.42m = 360

Solve this for m.
