Mandana is ordering new tile for her kitchen floor. The area of the floor is 116.4 square feet, and she wants to order between 15%
and 20% extra of the materials. Which of the following is a reasonable amount of tile for Mandana to order?

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
