There are two ways to do this:
Way 1- Since you know there are 4 people and each will pay 25%, you know that every person will pay equally / the same amount so you can just do 115/4 and get $28.75 per person
Way 2- You can convert 25% into a decimal by multiplying it by 100 and getting 0.25 and multiplying 0.25 x 115 to get 25% of 115, which is what everyone will pay and you get B $28.75
[tex]Each \: friend \: pays: \frac{25 \times 115}{100} = \frac{115}{4} = 28.75 \\ \Rightarrow B.\:\$28.75[/tex]
