Answer:
100$
Step-by-step explanation:
20% of 125 is 125x0.2 which is 25
so 125-25=100
3x+y=-5
12x+5y=27
Let y =-5-3x
Insert y into equ.2
12x+5(-5-3x)=27
12x-25-15x=27 den rearrange
-3x=2 den x =-2/3
Den put xinto equ 1
3(-2/3)+y=5
-2+y=5(collect like terms)
Y =7
.05 percent taxes if you spend 40 and 2 dollar worth of taxes
As a mixed number, it is 7 1/10 and as a fraction, in simplest form, it is 71 / 10
