Final answer:
After selling an average of 14 bushels each day for 5 days, the farmer will have 150 bushels left for sale.
Step-by-step explanation:
The farmer has 220 bushels of wheat to sell at his roadside stand. After 5 days of selling an average of 14 bushels each day, the total change in the number of bushels he has for sale can be determined by calculating the product of the average daily sale and the number of days, and then subtracting it from the initial number of bushels.
Total change = Initial number of bushels - (Average daily sale * Number of days)
In this case, the total change = 220 - (14 * 5) = 220 - 70 = 150.
