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.
<h3>Setting up proportion:</h3><h3>
![\frac{12}{9} = \frac{8}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B9%7D%20%3D%20%5Cfrac%7B8%7D%7Bx%7D)
</h3>
On cross-multiplying, we get
12x = 9×8
12x = 72.
Dividing both sides by 12, we get
![\frac{12x}{12} =\frac{72}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B12x%7D%7B12%7D%20%3D%5Cfrac%7B72%7D%7B12%7D)
x=6.
<h3>Therefore, Peter will pay $6 for 8 bunches.</h3>
