To find the total amount of people who like tacos, we can look at the table you provided.

The two-way table shows:

  • For 7th graders, the number of people who like tacos is not given.
  • For 8th graders, the number of people who like tacos is 35.

The total number of people who like tacos must also account for the missing value for the 7th graders. We can find it by using the totals provided.

The total number of people who like tacos according to the table is given as 71. We can confirm:

Total liking tacos = 7th graders liking tacos + 8th graders liking tacos
71 = (Number of 7th graders liking tacos) + 35

So:

Number of 7th graders liking tacos = 71 - 35
Number of 7th graders liking tacos = 36

Now, adding this to the 8th graders who like tacos:

Total who like tacos = 36 (7th graders) + 35 (8th graders)
Total who like tacos = 71

Therefore, the total amount of people who like tacos is 71.

The correct response is: 71
