Each roll costs $9 and each bow costs $1

3(9) + 5(1)= 32

Answer:

Each bow costs $1.

Each roll of wrapping paper costs $9.

Step-by-step explanation:

This question can be solved by a system of equations.

The problem says that:

x is the number of rolls of wrapping paper.

y is the number of bows.

You buy 3 rolls of wrapping paper and 5 bows for a total of $32.

This means that 3x + 5y = 32.

Your friend gets 1 roll of wrapping paper and 2 bows for $11.

This means that x + 2y = 11. So x = 11 - 2y.

Replacing in the first equation.

3x + 5y = 32

3(11 - 2y) + 5y = 32

-y + 33 = 32

y = 1

Each bow costs $1.

x = 11 - 2y = 11 - 2 = 9

Each roll of wrapping paper costs $9.
