Psychology Questions: 1. What is cost-benefit analysis in simple terms?
2. Should the benefit of study and cost of participants be equal in psychology, or should cost outweigh benefit the study, or should benefit stay outweighing cost?

      x/140 = 25/100

we need to find the x to find the x multiply 140 and 25

and what do you get 3500.   and what is 3500 divided by 100

= 35

i don't think so because different teachers have different materials. tehy teach differently, unless you know for sure your teacher is the exact same as others. i would just contact ur teacher
