10 bunches can be bought with $25
Here, we want to get a proportion that correctly represents the situation
From the question;
[tex]\begin{gathered} 4\text{ bunches = \$10} \\ 1\text{ bunch = }\frac{10}{4} \\ =\text{ \$2.5 per bunch} \end{gathered}[/tex]So now, let us get what is to be bought with $25
[tex]\begin{gathered} 1\text{ bunch = \$2.5} \\ x\text{ bunches = \$25} \\ x\text{ = }\frac{25}{2.5} \\ x\text{ = 10} \end{gathered}[/tex]The number of bunches that can be bought with $25 is 10
