To find out how many more avocados Phoenix consumes compared to Denver, expressed as a percentage, we can use the following steps:

Determine the avocado consumption for Phoenix and Denver from the chart:

Phoenix: 120 million

Denver: 75 million

Calculate the difference in consumption:

\[120 - 75 = 45 \text { million} \]

Express this difference as a percentage of Denver's consumption:

\[\left ( \frac { 45} { 75} \right ) \times 100 = 0.6 \times 100 = 60\% \]

Therefore, Phoenix consumes 60% more avocados per year compared to Denver. The correct answer is:

60%

**Supplemental Knowledge**

In percentage calculations, determining how much more one quantity is compared to another involves a few steps. First, you find the difference between the two quantities. Then, you divide this difference by the reference quantity (in this case, Denver's consumption) and multiply by 100 to convert it into a percentage.
