15 last year, jora spent
30% of his salary on rent
of his salary on entertainment
of his salary on living expenses.
he saved the rest of his salary.
jora spent £3600 on living expenses.
work out how much money he saved.

$378.95

Step-by-step explanation:

Change it all to fractions.

3/10 of her salary on rent

2/5 of her salary on entertainment

1/4 of her salary on living expenses.

Add them

3/10 + 2/5 + 1/4 = 6/20 + 8/20 + 5/20 = 19/20*S

(19/20)*S = 7200

S = 7200*20/19

She saved the remaining 1/20 of S = 7200/19

saved =~ $378.95

(-1,5)(2,4)
slope = (4 - 5) / (2 - (-1) = -1/3

y = mx + b
slope(m) = -1/3
use either of ur points (2,4)...x = 2 and y = 4
now sub and find b, the y int
4 = -1/3(2) + b
4 = -2/3 + b
4 + 2/3 = b
12/3 + 2/3 = b
14/3 = b

so ur equation is : y = -1/3x + 14/3however, this is not ur answer because it is not in standard form.

y = -1/3x + 14/3
1/3x + y = 14/3multiply both sides by 3
x + 3y = 14 <=== standard form
