Question 253380: at the beginning of the summer, sarah has $250. she takes a summer job and saves $150 per week. felicia has $1,650 at the beginning of the summer. she travels during the summer and spends $200 per week. write an equation that represents the amount of money sarah and felicia has at the end of each week.
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
at the end of each week, sarah has:

250 + (150*w)

at the end of each week, felicia has:

1650 - (200*w)

w = number of weeks.

at the end of the first week:

sarah has 250 + 1*150 = 400
felicia has 1650 - 1*200 = 1450

at the end of the second week:

sarah has 250 + 2*150 = 550
felicia has 1650 - 2*200 = 1250

etc.
