Steve started with $250 and spent $25 per week. Chelsea started with $30 and saved $30 per week. Use x for time and y for savings. How much money would be in their savings when it was the same amount?

the question is when are the two accounts equal... so our strategy is to find two equations and set them equal to each other

Step-by-step explanation:

weeks = w

steve's acct. = 250-25w

Chelsea's acct. = 30 +30w

so when do they equal

250-25w = 30+30w

now  solve for w

250-30 = 30w +25w

220 = 55w

4 = w

In four weeks.. they will have the same

so 250- 25(4) = 150  

and to check  30+30(4) = 150

so the each have $150.00 in their accts at 4 weeks

c. (3,2,6) is the answer.
