The scatter plot above displays the results of an experiment conducted by a hydroponics enthusiast to test the effect of fertilizer concentration on the yield of lettuce. Over the course of a month, she applied different concentrations of fertilizer (in grams per milliliter) to equal-sized sections of her farm and recorded the corresponding yield (in pounds).Note: 1 liter = 1,000 milliliters.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.
The fertilizer concentration that produces the maximum yield is g/mL, and if this concentration is used in a 25-liter tank, the total amount of fertilizer in the tank would be grams.

Official Solution:
From the scatter plot, the highest yield occurs at a fertilizer concentration of 0.16 g/mL, where the yield reaches 55 pounds. This is the maximum yield point, so the optimal concentration is 0.16 g/mL.
• Next, the total amount of fertilizer in a 25-liter tank at this concentration can be calculated as follows:
• 1 liter = 1,000 mL, so 25 liters = 25,000 mL
• Total fertilizer = concentration * volume
• Total = 0.16 g/mL * 25,000 mL = 4,000 grams
Correct answer:
Dropdown 1: "0.16"
Dropdown 2: "4000"

1. The apex of the graph, or when the yield is largest, is when the concentration is around 0.16 g/mL.
2. If we have 25L of the fertilizer, then there is 25000mL.
3. That means the total quantity of the fertilizer is equal to volume times concentration, or 25000mL\( * \)0.16 g/mL = 4000g.
4. Our answer will be: D1 - 0.16 and D2 - 4000.
