Heathers weekly pay is directly proportional to the number of hours she works at the record store. her pay is $174 for 24 hours of work. find the amount of pay for 40 hours of work.
how do you solve this ?

Let,
the pay for 40 hours be "x",
Since the weekly pay is directly proportional to the number of hours she works at the record store, using ratio and proportion, we can write,
 
        
Using cross multiplication,
        
 
        

So, the amount of pay for 40 hours of work is $290

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
