Question

At Print All copying, a new copying machine can produce five more than twice the number of copies per hour of the old copy machine. If the new machine produces 205 copies per hour, how many copies can the old machine produce? Show the equation you used to determine the answers.

Answer 1

205 - 5 = 200
200/2 = 100 copies per hour

Answer 2

Old machine can produce 100 copies per hour.

Explanation:

Let the number of copies produced by old machine = x per hour

As per statement given in the question, " new copy machine can produce 5 more than twice the number of copies per hour of the old copy machine".

Number of copies produced by new machine = (2x + 5) copies

New machine produces 205 copies per hour.

Therefore, (2x + 5) = 205 will be the equation.

Now we solve this equation to get the value of x.

2x = 205 - 5

2x = 200

x =
`(200)/(2)=100` copies.

Old machine can produce 100 copies per hour.
