At 8:15 p.m. on April 30, 2022, the population of the United States was 332,637,800. There is one new person in the United States every 61 seconds. Write a linear function to model the population of the United States as a function of the number of seconds that has passed since 8:15 p.m. on April 30, 2022.

O f(x)=61x+332,637,800
O f(x)= 1/61 x+332,637,800
O f(x)=332,637,800x+ 1/61
O f(x)=332,637,800x+61
