Answer:

$5

Step-by-step explanation:

Set up a system of equations

let b be the cost of a bow

let w be the cost of a roll of wrapping paper

This means that

[tex]5b + w = 10\\b + w = 6[/tex]

Subtract the two equations

[tex]5b + w = 10\\- (b + w = 6)\\4b = 4\\b = 1[/tex]

Plug this into the equation b + w = 6

1 + w = 6

w = 5.

This means the cost of a bow is $1 and the cost of a roll of wrapping paper is $5.
