So this right over here is 1,400. And so we have W prime at time equals zero. So our slope at time equals zero, our derivative at time equals zero, is equal to one over 25 times 1,400 minus 300 is 1,100. Minus 300 is 1,100. And 25 goes into 1,100, it goes into 1,100 44, it would go into it 44 times, right? It goes four times into each 100. We have 1,100 here, so it'll go 44 times.
