Question

Administrators at a local high school are organizing desks in the cafeteria for the junior students to use while taking a practice SAT test. Due to space limitations, there should be fewer than 264 students in the cafeteria. The administrators want there to be 13 less rows than the number of desks in each row.

If d represents the number of desks in each row, which inequality could represent this situation?

Answer 1

correct choice is B

Explanation:

If d represents the number of desks in each row and the administrators want there to be 13 less rows than the number d of desks in each row, then the number of rows is d-13.

The total number of desks in all rows is

`d\cdot (d-13)=d^2-13d.`

Due to space limitations, there should be fewer than 264 students in the cafeteria. Therefore,

`d^2-13d<264.`
