Answer:
70% of people surveyed liked the plan.
Explanation:
Given that,
No. of people that liked the plan = 2,800
No. of people that did not like the plan = 1,200
We need to find what percentage of the people surveyed liked the plan. It can be given by :
![\%=(2800)/(2800+1200)* 100\\\\=70\%](https://img.qammunity.org/2022/formulas/mathematics/high-school/h0vwx26hm5ufb5z0ydbgswp83fq2tjfy4o.png)
