Step-by-step explanation:
The student's question involves a business decision regarding which crop to grow for maximum profitability on the Stinson family farm. To advise accurately, one would calculate the net profit per acre for each option: wheat, barley, and leasing. For wheat, the net profit is calculated by multiplying the yield (70 bu/acre) by the price ($3.50/bu) and subtracting the expenses ($140/acre), resulting in a net profit of $105 per acre. Similarly, for barley, the net profit is the yield (50 bu/acre) multiplied by the price ($2.50/bu) minus the expenses ($150/acre), totaling $25 per acre. Finally, leasing yields a net profit of $80 per acre less expenses of $35, amounting to $45 per acre. Comparing the three net profits, growing wheat yields the highest profit of $105 per acre.
