Assuming you meant:
480 - 8t - .8t^2 or R1
sub in all the values of t into R1, then add them up
sub in all the values of t into R2, then add them up
compare the two answers.
You own two restaurants. From 1995 to 2000, the sales R1 (in thousands of dollars) for one restaurant can be modeled by:
R1 = 480 – 8t – 0.8t2, t = 0, 1, 2, 3, 4, 5, where t = 0 represents 1995.
During the same 6-year period, the sales R2 (in thousands of dollars) for the other restaurant can be modeled by:
R2 = 254 + 0.78t, t = 0, 1, 2, 3, 4, 5
Write a function R3 that represents the total sales for the two restaurants.
