Question

Tom needs to clean 50 square ft of carpet. One bottle of will clean 1 1/2 square ft of carpet. how many bottles will he need

Answer 1

Total is 50 sq ft.

one bottle will clear 1 1/2, sqft .

Let x be the number of bottles needed to clean 50 sqft.

So taking the proportion,

`\begin{gathered} (1)/(1(1)/(2))=(x)/(50) \\ (1)/((3)/(2))=(x)/(50) \\ 50=(3)/(2)x \\ x=(2*50)/(3)=33.33 \end{gathered}`

Therefore the number of bottles needed is 34
