So, Linda already had $650 dollars in her account, but the question isnt asking you how much she already had. Its asking how much she's getting per week 1 year ago OpenStudy (legomyego180): |dw:1470610243762:dw| 1 year ago OpenStudy (flvskidd): I cant see the third box 1 year ago OpenStudy (legomyego180): It just says what already in the bank. Lets say every week I give you$5. How can you tell how much money i've given you after four weeks?

multiplication

OpenStudy (legomyego180):

right 4 times 5. If you wanted to tell how much I'd given you in nine weekd you'd do 9 times 5. If you wanted to find out how much I'd given you in 100 weeks you'd multiply 100 times 5 So you can see the 5 is always staying the same because I'm never giving you more, or less than $5. But the week does change... 1 year ago OpenStudy (legomyego180): so to represent that we just make a rule: I can see how much money i've made by multiplying 5 by however many weeks I've been working. Or How Much I've Made =$5 x Number of weeks. It's kind of annoying to write this out every time so we make a code system: y=how much money you've made. x=number of weeks you have worked So we can say: y= $5x 1 year ago OpenStudy (flvskidd): okay 1 year ago OpenStudy (legomyego180): Last thing, lets say you already had$50 and you wanted to see how much money you had on top of what I was giving to you per week. You would do the same equation: y=5x but you would need to add \$50 to it to get the total amount you have now. y=5x+50 See the pattern?
