In the year 2000, the average American consumed 8.3 gallons of whole milk per year. This amount has been decreasing by 0.3 gallons per year. Which inequality can be used to find the number of years, t, since 2000 in which whole milk consumption was greater than 6.0 gallons per person per year?Choose 1 answer:(A) 8.3-0.3 t>6.0 (B) 8.3-0.3(t-2,000)>t (C) 8.3-0.3 t<6.0 (D) \( 8.3-0.3(t-2,000)
Q. In the year 2000, the average American consumed 8.3 gallons of whole milk per year. This amount has been decreasing by 0.3 gallons per year. Which inequality can be used to find the number of years, t, since 2000 in which whole milk consumption was greater than 6.0 gallons per person per year?Choose 1 answer:(A) 8.3−0.3t>6.0(B) 8.3−0.3(t−2,000)>t(C) 8.3−0.3t<6.0(D) 8.3−0.3(t−2,000)<t
Given Information: We are given that the average American consumed 8.3 gallons of whole milk in the year 2000 and that this amount decreases by 0.3 gallons each year. We need to find the inequality that represents the years, t, since 2000 when the consumption was greater than 6.0 gallons.Let's start by setting up an equation that represents the consumption of whole milk in any year after 2000.Initial consumption in 2000: 8.3 gallonsDecrease per year: 0.3 gallonsNumber of years since 2000: tConsumption in year t: 20003We want to know when this consumption is greater than 6.0 gallons.So, the inequality will be:20005
Setting up Equation: Now, let's check the answer choices to see which one matches our inequality.(A) 8.3 - 0.3t > 6.0 matches our inequality.(B) 8.3 - 0.3(t-2,000) > 6.0 is incorrect because it incorrectly subtracts 2,000 from t, which is not necessary since t represents the number of years since 2000.(C) 8.3 - 0.3t < 6.0 is the opposite of what we want; we are looking for when consumption is greater than 6.0 gallons, not less.(D) 8.3 - 0.3(t-2,000) < 6.0 is incorrect for the same reason as (B) and also because it represents an inequality where consumption is less than 6.0 gallons.
