Answer:
Savings % = 40%
Monthly income = Rs 20,600
Amount spend = Rs 12,360
Step-by-step explanation:
Let the percentage savings be 's'
Percentage savings = 60% + s = 100
s = 100 - 60
s = 40%
This is because, percentages sum up to hundred (100)
Let her monthly income be I
40/100 × I = 8240
40I/100 = 8240
40I = 824000
Divide both side by 40
I = Rs 20,600
Therefore her monthly income is Rs 20,600
Amount she spends
20,600 - 8240
= Rs 12,360
Or 60/100 × 20,600
= Rs 12,360
3y + 9x = 12
3y = -9x + 12
y = -3x + 4
If you want function notation you can replace y with f(x)
f(x) = -3x + 4
