You start a bank account with $25. Then, each week you deposit $15. How many weeks will it take to have $235 in the account? A. 14 B. 17 C. 17.3 D. 10
how would you set this up as an equation?
i dont even know
well lets look at it, what is something that stands by itself(no number or variable will be paired with it)
x ?
no in your problem...what number given wont be affected by any other?
it would be the starting value right?
yes so 25 ?
okay so you have that figured out. now it tells you you put in 15 each week so how would you represent that?
25 *15 ?
no, the 25 stands alone. for example it will look like 25+?
so 25+?=15 ?
no. it is going to be equal to 235 since that is the TOTAL. the 25 is the STARTING NUMBER of the account and then the 15 is the amount WEEKLY added.
oh okay let me try this again lol
25+?=235 ?
yes! now for the question mark part of 25+?=235. you know that you put 15 in each week, and the question is asking you how many wees it will take you to get to your TOTAL. so how would you represent that portion?
25+15=235 ?
the 15 needs to have a variable with it so you can solve for it.
25+15x=235
yes! so now from there what would we do?
its 14 :)
congrats :D
