Hi Christopher,
the problem tells us that this linearly related. So we need to find the average rate for each refrigerator and what the y intercept is when no refrigerators have been sold.
The number of refrigerators is the independent variable and the cost is the dependent variable. So we have two ordered pairs.
Slope or m is the difference between the two costs divided by the number of refrigerators.
Take this number which is 60 and then plug it into y= mx+b using one set of your ordered pairs (52,4195) or (108, 7555) to get your y intercept.
C = 60x + 1075
hope this helps.

The population of a small town in central Florida has shown a linear decline in the years 1987-1997. In 1987 the population was 33500 people. In 1997 it was 28000 people. A) Write a linear equation expressing the population of the town P,in terms of t ,the number of years since 1987.B) If the town is still experiencing a linear decline, what will the population be in 2002?06/02/20
