Known facts:

  • 50 dollars is the initial amount in the saving account
  • 50 dollars is added every week into the savings account.

Variables:

  • y: total amount of money in savings

Set equation based on known facts and variables:

y = 50x + 50, 50x is the rate at which it grows depending on

the week and 50 is the initial amount there

Hope that helps!
