1. Question:

Mandana is ordering new tile for her kitchen floor. The area of the floor is 119.9 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?

A.
134 square feet

B.
140 square feet

C.
137 square feet

D.
145 square feet

B.  140 square feet   is a reasonable amount of tile for Mandana to order

Step-by-step explanation:

Total area of the floor  = 119.4 square feet

If Mandana is ordering 15% extra, the the tile will be

=  119.4 +  15% 119.4

=  $$119.4 + \frac{15}{100} \times 119.4$$

= $$119.4 + 0.15 \times 119. 4$$

= 119.4 + 17.91

=137.31  square feet

If Mandana is ordering 20% extra, the the tile will be

=  119.4 +  20% 119.4b

= $$119.4 + \frac{20}{100} \times 119.4$$

= $$119.4 + 0.2 \times 119. 4$$

= 119.4  + 23.88

= 143.28  square feet

Thus from the options

134<  137<  137.31 <  140< 143.28<  145
