Complete Question:
Mrs. Roberts plants tomatoes and radishes in the areas shown in the model below.
![Tomatoes: 35\ acres](https://img.qammunity.org/2021/formulas/mathematics/high-school/a5hipqg9ltsnwxz3vx504cue0cidezva6m.png)
![Radishes: 28\ acres](https://img.qammunity.org/2021/formulas/mathematics/high-school/5l982tn7lkjk8wefx1lk2mpflh1jc8zt4h.png)
Which expression is equivalent to the sum of the two areas?
Answer:
![A + B = 63](https://img.qammunity.org/2021/formulas/mathematics/high-school/1hlkdqia88y61wsdc6cv5mv4ur82z1qe6e.png)
Explanation:
Given
Represent the area of Tomato with A and area of Radish with B
So:
![A = 35](https://img.qammunity.org/2021/formulas/mathematics/high-school/10o11pssxnkymkf5otrk7rllu57m54anpy.png)
![B = 28](https://img.qammunity.org/2021/formulas/mathematics/high-school/o7skaprxqb7dkbad6gk42anqd03vntdzv2.png)
The sum of the two areas is therefore:
![Sum = A + B](https://img.qammunity.org/2021/formulas/mathematics/high-school/qstn1c2xr32kys970n3kxr0l1h4cax33y6.png)
Substitute 35 for A and 28 for B
![Sum = 35 + 28](https://img.qammunity.org/2021/formulas/mathematics/high-school/hs0ztsigpjxi90p4lhxzdk60zm5nfapkjm.png)
![Sum = 63](https://img.qammunity.org/2021/formulas/mathematics/high-school/zo857uzqvapulzoiwuy5ezbx39dgkxa4o3.png)
So, you either represent the model as:
![Sum = 63](https://img.qammunity.org/2021/formulas/mathematics/high-school/zo857uzqvapulzoiwuy5ezbx39dgkxa4o3.png)
or
![A + B = 63](https://img.qammunity.org/2021/formulas/mathematics/high-school/1hlkdqia88y61wsdc6cv5mv4ur82z1qe6e.png)
