Brand x copier has improved its copier so that it produces 10% more copies than its old model. if the old model ran 420 copies per hour, how many copies would the new model run? round your answer to the nearest whole number.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8

Ithink it's the first one ( let me know if it right)
