Question 27 • Mathematical Models with Applications - MA4072 CR

A scientist suggests keeping indoor air relatively clean as follows: Provide two or three pots of flowers for every 100 sq ft of floor space under a ceiling of 8 ft. If your classroom has an 8-ft ceiling and measures 35 ft by 40 ft, how many pots should it have?

Answer
A
37-56 pots
B
26-39 pots
C
28-42 pots
D
27-36 pots

Explanation

The classroom floor area is 35 × 40 = 1,400 square feet, or 14 sections of 100 square feet. At 2 to 3 pots per section, it needs 14 × 2 = 28 to 14 × 3 = 42 pots. The correct choice is 28–42 pots.
