The scatterplot displays the number of pretzels students could grab with their dominant hand and
their handspan, measured in centimeters. An analysis
was completed and the computer output is shown
Using the computer output, the slope of the least-
squares regression line means for each additional
pretzel, the handspan will increase by about 1.585
cm.

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 : )
