Savings Application Devin has $100 in savings and is planning to add $50 each week. Laura has $400 in savings
and is planning to add $40 each week. Their plan is to wait until their savings are equal
and then load up their old Volkswagen bus and take a road trip. They figure out that the
equation used to determine how many weeks it will take until their savings are equal is
50w + 100 = 40w + 400, where w is the number of weeks they have been saving.
How many weeks will Devin and Laura have to continue to save until they both have the
same amount in savings and they can go on their road trip?
Devin and Laura will have the same amount in savings after
weeks
