Answer: 136 copies in 4 minutes and 15 seconds
Explanation:
First, we need to find how many copies the machine makes per second
a minute has 60 seconds. Divide the number of copies made per minute by 60
32/60
simplify
8/15
It can make 8/15 copies per second.
It takes a minute to print 32 copies, so multiply the number of copies per minute by 4 minutes
32*4=128
128 copies in 4 minutes
now 8/15 * 15 =120/15 = 8
128+8=136
