Question

Dakota has $2 in her saving account, but each week she adds $3. How much money does Dakota have after 5 weeks? after n weeks?

Answer 1

She starts with $2 and adds $3 every week, so she has  2+ 3*5 = $17 after  5 weeks

 

So we can see for any amount of weeks (n) she'll have:  total $ = 2 + 3n
