Question

Translate to an equation:

f $0.30 folders and n $1.50 notebooks total $12

Answer 1

.30f+1.50n=12

Answer 2

yes

Answer 3

you need solve for n and f?

Answer 4

Yes. I have to graph the equation and use the graph to determine three different combinations of folders and notebooks that total $12

Answer 5

Ok, give me a minute I have to write on my paper first

Answer 6

subtitution: f=12-n
0.3(12-n)+1.5n=12
3.6-0.3n+1.5n=12
1.2n= 12- 3.6
n=8.4/1.2
notebooks = 7
subtitution notebooks = 7 find folders
0.3f+1.5(7)=12
0.3f +10.5 =12
0.3 f=12-10.5
f= 1.5/0.3
folders = 5
