Final answer:
Ping-Lin should expect a total amount of approximately 29.26 kilograms of peas from the tract of land if he applies the fertilizer.
Step-by-step explanation:
To calculate the total amount of peas that Ping-Lin should expect after applying the fertilizer, we need to find a 10% increase in the yield of 26.6 kilograms.
First, we calculate 10% of 26.6 by multiplying 26.6 by 10% (0.10). This gives us 2.66 kilograms.
Next, we add the 10% increase to the original yield of 26.6 kilograms:
26.6 + 2.66 = 29.26
Therefore, Ping-Lin should expect a total amount of approximately 29.26 kilograms from this tract of land after applying the fertilizer.
