a: what was the approximate revenue from licenses in 1990?

b: write an equation that gives the revenue as a function of the number of years since 1990.

c: find the revenue from licenses in 1999.

1 answer

a. y = mx + b

15099 = 499.79(10) + b
b = 10101.1
y = 499.79x + 10101.1

b. y = 499.97x + 10101.1
y = 499.79(0) + 10101. 1
y = $10101.1
c. y = 499.79x + 10101.1
y = 499.79(9) + 10101.1
y = $14599.21
