Will is playing the stock market game he starts out with a stock value at $68.25 at the beginning of day at the end of rach of the four days he records the change in the price of the stock the changes he records I listed in the chart below but there is some missing information the chart the change in price for day two is 1/5 of days once change the dates for changes twice days three what is the amount in dollars well has at the end of day four

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
