Question 930428: james and max are saving up their allowances to buy laptop computers. James has to saved $30 already and a $5 allowance each week. Max has saved $10 already and earns a $10 allowance each week.
Explain how do you know if the linear systeam will have one solution no solution, no solution
Slove your systeam algbraically using either substitution method or the elimination method
after many more weeks will james and max have saved the same amount of money? how did the graph help you determine your answer
Did you find it easier to solve the liner systeam algebraically or graphically? explain why.

You can put this solution on YOUR website! james and max are saving up their allowances to buy laptop computers.
James has saved $30 already and a $5 allowance each week.
y = 30 + 5x
--------------------
Max has saved $10 already and earns a $10 allowance each week.
y = 10 + 10x
--------------------
Explain how do you know if the linear systeam will have one solution no solution, no solution
Ans: One solution because the equations have different slopes.
---------------------
Solve your systeam algbraically using either substitution method or the elimination method
30+5x = 10 + 10x
5x = 20
x = 4 weeks
===================
After how many more weeks will james and max have saved the same amount of money?
ans: 4 weeks
--------------------
How would a graph help you determine your answer?
Ans: Find the x=value of the point of intersection of the graphs.
-----------------------
Would you find it easier to solve the liner systeam algebraically or graphically? explain why.
Ans: Algebraic----Graphing takes more time and it is hard to
be sure what the point of intersection is.
