Answer 1

7 students from Manuel's class, representing 25% of the 28 total students, went to the library last weekend. The correct answer is B.

Step-by-step explanation:

The question relates to finding a percentage of a given quantity. In this case, we calculate 25% of Manuel's classmates who went to the library. Since there are 28 students in Manuel's class, we calculate the number of students who visited the library as follows:

1. Write the percentage as a decimal: 25% = 0.25.
2. Multiply the decimal by the total number of students: 0.25 × 28 = 7.

Therefore, 7 students from Manuel's class went to the library last weekend, which corresponds to answer B.
