Question

At PrintAll 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

The old machine can produce 100 copies/hour

Explanation:

x= number the old machine can produce per hour

2x+5=205

2x=200

x=100

Answer 2

100

Explanation:

take the words 5 more or plus 5+, than twice (2) a number or the amount the old machine can use (x). put it together to get 5+2x now the new one can produce 205 copies total. we use total as equal so, 5+2x=205, subtract 5 on both sides. 2x=200 and divide by 2 to both sides. x=100
