Question

Expressed as a percentage, how many more avocados does the city of Phoenix consume per year compared to Denver? 20% 36% 40% 54% 60% Submit AnswerSHOW LESS158

Solution

40%

To find the percentage difference in avocado consumption between Phoenix and Denver, we need to calculate the difference and express it as a percentage of Denver's consumption.

Let's assume Denver consumes x avocados per year and Phoenix consumes y avocados per year.

The difference in consumption is y - x.

To express this as a percentage of Denver's consumption, we divide the difference by x and multiply by 100.

Percentage difference = (y - x) / x * 100

Since the question asks for the percentage more that Phoenix consumes compared to Denver, we can rearrange the equation to solve for y:

y = x + (x * percentage difference / 100)

Let's assume the percentage difference is p.

y = x + (x * p / 100)

Now, we can substitute the given answer choices to find the correct percentage difference.

20%: y = x + (x * 20 / 100) = x + 0.2x = 1.2x

36%: y = x + (x * 36 / 100) = x + 0.36x = 1.36x

40%: y = x + (x * 40 / 100) = x + 0.4x = 1.4x

54%: y = x + (x * 54 / 100) = x + 0.54x = 1.54x

60%: y = x + (x * 60 / 100) = x + 0.6x = 1.6x

Comparing these equations, we can see that the correct answer is 40%.
