Answer 1

Given:

A copier uses 30 grams of toner to produce 1000 copies.

Required:

To find the number of grams are required to produce 2500 copies.

Step-by-step explanation:

Let x be the number of grams are required to produce 2500 copies.

Now the number of grams are required to produce 2500 copies is

`\begin{gathered} (30)/(x)=(1000)/(2500) \\ \\ 30*2500=1000* x \\ \\ 1000x=75000 \\ \\ x=(75000)/(1000) \\ \\ x=75 \end{gathered}`

Final Answer:

75 grams are required to produce 2500 copies.

`(30)/(x)=(1000)/(2500)`

OR

`(1000)/(30)=(2500)/(x)`

The option D is correct.
