From the early 1970s through 2010 in the US, the enrollment of 3-4 year olds has steadily increased. In 1970, 20% of 3 - 4 year olds were enrolled in Pre-K while in 2010, the Pre-K enrollment of 3 - 4  year olds was 53%. Write a linear equation that would model this data where t = time in years after 1970 and P is the rate of 3 - 4 year old enrollment in pre-K as a percentage.       P = 0.825t +20     P = 0.825t - 53     P = -0.825t +20     P = 0.825t + 53     P = 0.825t -20

Question

From the early 1970s through 2010 in the US, the enrollment of 3-4 year olds has steadily increased. In 1970, 20% of 3 - 4 year olds were enrolled in Pre-K while in 2010, the Pre-K enrollment of 3 - 4  year olds was 53%. Write a linear equation that would model this data where t = time in years after 1970 and P is the rate of 3 - 4 year old enrollment in pre-K as a percentage.

 
   

P = 0.825t +20

   

P = 0.825t - 53

   

P = -0.825t +20

   

P = 0.825t + 53

   

P = 0.825t -20
