So three times, so when T is zero, G is 91. 91 minus 27 to the 1 3rd power is equal to negative T. Well now we're saying T is zero, so we could write negative zero there, or we could just not write it, and then plus C. So that's what C is going to be equal to. Let's see, 91 minus 27 is 64. 64 to the 1 3rd power is positive four, and so we have C is equal to 12. C is equal to 12, and let's see. We want to write an expression for G of T, so now let's just manipulate this and solve for G. So if we, so let me just take this and go right over here. So if we divide both sides by three, we are going to get G minus 27 to the 1 3rd power is equal to negative T over three plus four.
