Answer 1

227 500

Explanation:

let x represent the numbear of people suffering from this allergen in U.S

7—————>10,000

x—————>325,000,000

then

x = (325 000 000×7)÷10 000 = 227 500

Answer 2

Answer:2275000

Explanation:

If out of 1000, 7 people are being affected. It means that (7/1000)*100= 0.7% of the population is being affected

Since USA poppulation is 325million, the affected people are 0.7% of 325 million

325000000*(0.7/100)= 2275000
