Millie and Samantha begin saving money at the same time.Millie plans to save $3 a month, and Samantha plans to save $6 a month. After how many months will Samantha have $30 more than Millie?
okay, you can try out"how much will they both save after 12 months" and see that sam will save 72(6$*12 months) and millie saves(3*12)=36. so try 11 months. that gives you 66 and 33 so try 10 months and you see that 60$ and 30$ is a difference of 30$; so it will be after 10 months
