<em>Answer:</em>
<em>The energy intake from food is measured in Calories (Cal). It is to be distinguished from the calorie (with a small 'c'), which is also frequently used in technical publications. The Calorie is equal to 1 kilocalorie. The conversion formula between the Calorie and the Joule is:</em>
<em>1 Cal = 4184 Joules</em>
<em>Step-by-step explanation:</em>
<em>First let's find the total energy intake from the candy bar :</em>
<em>E = 2 × 1.2 10^6 </em>
<em>J = 2.4 × 10^6 J.</em>
<em></em>
<em>
And the total energy intake from the soft drink is :</em>
<em>E = 3 × 6.7 × 10^5 </em>
<em>J = 2.01 × 10^6 J.</em>
<em />
<em>The total energy consumed is :</em>
<em>E = 2.01 × 10^6 + 2.4 × 10^6 </em>
<em>J = 4.41 × 10^6 J.</em>
<em></em>
<em>The person is on a 2000 Cal diet. This converts to :</em>
<em>2000 × 4184 </em>
<em>J = 8.368 × 10^6 J.</em>
<em></em>
<em>The amount of energy intake left for broccoli, beans, beef, etc is :</em>
<em>(8.368 - 4.41) × 10^6 </em>
<em>J = 3.958 × J.</em>
<em />
<em>As a percentage of the total food intake, we can write this as :</em>
<em>3.958/8.368 × 100% = 47.3%</em>
<em />
<em>So now we got our final answer :</em><em> 47.3%</em>
