Answer:

Equation: 500 = 50 + 15x

Step-by-step explanation:

where x is the number of weeks Nick will have to deposit $15 in order to accumulate $500, given that the first week he deposited $50.  

500 = 50 + 15x

500 = 50 + 15x

450 = 15x

x = 30

 

Now Nick will have to deposit $15 each week for 30 weeks.   This is in addition to the $50 deposit he made week 1.  So it will take him 31 total deposits to accumulate the $500.
