Answer:
36 copies.
Step-by-step explanation:
4mins 15 seconds is the same as 4+1/4 minsutes. Since 1 minute is less than 4+1/4minutes and 4+1/4 minutes produces 153 copies. 1 minute will produce less.
(1÷4+1/4)×153
= 36 copies.
36
Change the time into seconds so they’ll be in the same unit, (4*60) + 15= 255. Do cross multiplication,
153. 255
? 60
(153*60) / 255= 36
