 Use systematic sampling to select 50 individuals from a group of 1000 for a survey. Each person is assigned a random number from 1 to 1000. After forming appropriate groups, the number drawn from the first group using simple random sampling is 8. From the 50 people selected, those with numbers in the interval $[1,400]$ will answer survey A, those with numbers in the interval $[401,750]$ will answer survey B, and the remainder will answer survey C. Calculate the number of selected individuals who will answer survey C. Express your answer as a whole number. Show your work in <think> </think> tags.
