Asap here quickly! im bad at this

1) Since it was 0 years when the college opened, we put x=0 and we get

T=12000

2) 0.03%

3) From 1990 to 2020, it is 30 years. Thus, x=30.

T=12000*(1.03)^30

For calculations for the 2nd point, refer to the picture.

Hope this helps!

For future whenever you solve these type, just know that x is a variable and tree have to insert out own value for x according to the questions’s demand.

a² + b²= c²

24² + 7² = c²

c= 25
