Jan had the same summer job for three years 1993 through 1996, earning $250 in 1993, $325 in 1994, $400 in 1995 ,and $475 in 1996.
a. what is the slope of this line? what does it represent?
It is 75 and it represents the yearly increase.
b. What points on this line are meaningful in this context?
Aren't they all equally meaningful?
c. Guess what Jan's earnings were for 1992 and 1998, assuming the same summer job.
1992 = $175 1998 = $625
d. Write an inequality that states that Jan's earnings in 1998 were within 10% of the amount you guessed.
This is the question i really needed help on.
I set up l 625 - X l < 62.5
-62.5 < 625 - X < 62.5
562.5 < X < 687.5
Is this correct?
