Aiden has saved $85 per month for the past 7 months. He plans to save the same amount each month in the future until he has saved a total of $1955 for a new computer. For how many additional months will Aiden need to save?
once you put the question as an actual question (85(7+m)=1955), you need to get rid of the 85 so you divide 85 by 85 which cancels it out. then you need to do the same to the other side (1955) 1955/85 is 23. you should be left with 7+m=23. now we need to get rid of the constant, which is 7. you do 7-7 and you do the same with the other side, 23-7. you should be left with your answer, m=16.
answer: m=16
