Question

I don't understand it i'm 10. Coach Scott had 1,750 bean bags. Coach Schemer had 1,270 bean bags. Then Coach Scott gave bean bags to Coach Schemer. Now Coach Schemer has 3 times as Coach Scott. How many bean bags does Coach Schemer have. 

Answer 1

b represents the number of bags given away (and gotten).

Scott 1750 - b

Schemer 1270 + b

 

Now Schemer = 3 times Scott

1270 + b = 3(1750 - b)

 

Can you solve for b and answer?
