Problema Solution
Aidan started a savings account. He started with some money his grandmother gave him and then added the same amount each week from his babysitting earnings. what is the dependent variable?
Answer provided by our tutors
the dependent variable f(x) is the personal savings in relation to the time t passed, t is independent
beginning moment t = 0
f(0) = c, where c is the money grandmother gave to Aidam that is C = constant
after 1 week t = 1
f(1) = f(0) + c = 2*c
after 2 weeks t = 2
f(2) = f(1) + c = 3*c
after t = n weeks time
f(n) = (n+1)*c
