In this question, we have to find the difference in revenue.
00:03
Area between both the curves will give us the revenue difference in both the models given for year 2015, t which is equal to zero.
00:47
And year 2021 t which is equal to 6, 2024 t which is equal to 9.
00:57
Area between both curves from t which is equal to 6 to 9 will be difference in revenue which is equal to integral t to t to revenue r1 t subtracting r2 t which multiply by d t now substituting the curves in this formula, we get 629, 5 .13 add with 0 .22t, add with 0 .06 t power 2.
01:46
Subacting 5 .13, add with 0 .11t, add with 0 .01 t power 2, which multiply by dt.
02:00
So simplifying this one, we can return integral 629, 0 .11t, add with 0 .05 t power 2, which multiply by dt.
02:13
Now integrating this equation, we get 0 .11 t power 2, which is 2...
