Question 131785: I am sorry but this question does not come from a text book. It is from a handout provide by the teacher. The question is for Algebra 1, my son is a freshman.
Here is the Question:
For 1990 through 1999, the number of indoor movie screens I and total movie screens T is modeled by:
I=161.6t^2 - 20t + 23,326
T=160.3t^2 - 26t + 24,226
where t is the number of years from 1990 inclusive.
Find a model for the number of outdoor movies screens D in the US for this time frame.

I=161.6t^2 - 20t + 23,326
T=160.3t^2 - 26t + 24,226
.
In this case t=10
161.6*10^2-20*10+23326
=161.6*100-200+23326
=16160-200+23326
=39286=I
.
160.3*10^2-26*10+24226
=160.3*100-260+24226
=16030-260+24226
=39996=T
.
T-I=D Model for the number of outdoor screens. Answer.
39996-39286=710 Number of outdoor screens 1990-1999 inclusive.
