Answer: the total number of entries at the fair is 350
Step-by-step explanation:
Let x represent the number of entries that were there at the fair.
At a county fair, 50% of the entries are livestock. This means that the number of livestock at the fair was
50/100 × x = 0.5x
Of those entries, 80% are sold at the auction. This means that the number of entries that were sold at the auction is
80/100 × 0.5x = 0.4x
If 140 entries of livestock are sold at the auction, it means that
0.4x = 140
x = 140/0.4
x = 350

Answer:
the slope is defined as the change in price divided by the change in quantity supplied between two points (i.e. the two ordered pairs). we can use the following formula to calculate it: m = (y2 – y1)/(x2 – x1). in the case of my example, the two ordered pairs are (2, 500) and (1, 250)
