t it is not in my problem.

Answer 4

let x for 12% =0.12
let y for 6% = 0.06
7%=0.07
x+y=240
x = 240-y
0.12x+ 0.06y= 0.07* 240
can you solve from now?

Answer 5

17.8?

Answer 6

subtitution x = 240-y
0.12(240-y)+ 0.06y= 0.07* 240
28.8 - 0.12y +0.06y = 16.8
-0.06y =16.7-28.8
y = -12/-0.06
y = 200

Answer 7

x+y=240
subtitution y= 200 solve for x
x+200=240
x = 240-200
x = 40
