This becomes 10:22, then 5:11.
Answer:
$1.89
Step-by-step explanation:
1) 8p+3f=$10.39
2) 5p+4f=$10.51
where p represents pencil & f represents folder.
multiply the first equation by 5 and the second equation by 8.
40p+15f=$51.95
40p+32f=$84.08
Subtract
17f=$32.13
f=$32.13/17 =$1.89
The answer is no solutions
27/0.30 = 90
The answer is 90
