Maya and Sally were the two finalists in a singing competition. The person with the most votes from the audience was chosen as the winner. Sally received 25% of the total votes and lost by 62,500 votes. No person in the audience was allowed to vote more than once. The equation below represents this situation, where y is the total number of votes cast and x is the number of votes Maya received. x - 62,500 = 0.25y If a total of 125,000 people voted, how many votes did Maya receive?

Le gasp :) I kinda like age problems, so let's settle things between ol' Coach Johnson and Tim ^_^

OpenStudy (anonymous):

ok!

terenzreignz (terenzreignz):

The first step to word problems like these is to represent values.. We're looking for Tim's age, so we might as well let Tim's age be x. Okay? :)

OpenStudy (anonymous):

yea!

terenzreignz (terenzreignz):

So, what is Coach Johnson's age?

OpenStudy (anonymous):

ten years younger then x

terenzreignz (terenzreignz):

Younger??

OpenStudy (anonymous):

terenzreignz (terenzreignz):

Older... so what is the coach's age in terms of x?
