We are given that Peter buys 12 bunches of bananas for 9.00.

We need to determine how much peter will pay for 8 bunches.

Let us set up proportion now.

12 bunches of bananas for 9.00 = 12 : 9

Let us assume Peter will pay for 8 bunches = $x.

Therefore, 8 bunches of bananas for x = 8 : x.

Setting up proportion:

[tex]\frac{12}{9} = \frac{8}{x}[/tex]

On cross-multiplying, we get

12x = 9×8

12x = 72.

Dividing both sides by 12, we get

[tex]\frac{12x}{12} =\frac{72}{12}[/tex]

x=6.

Therefore, Peter will pay $6 for 8 bunches.
