Me im begging
me its easy use the information about music sales on page 402 to explain how you can use polynomials to model sales. include an equation that models total music sales, and an example of how and why someone might use this equation in your answer.

this is the thingy

from 2000 to 2003 the amount of sales (in millions of dollars) of rap/hip-hop music r and country music c in the united states can be modeled by the following equations, where t is the number of years since 2000
r= -132.32t^3 + 642.74t^2 -773.61t+ 1847.67
c= -3.42t^3 +8.6t^2-94.95t+1532.56
the total music sales t of rap/ hip hop and country music is r+c
