Answer:
1190
Step-by-step explanation:
We have the ratio: 8:340 which means that 340 copies are printed in 8 minutes
We want to find out how many color copies are printed in 1 minute so we divide by 8
so our new ratio is now 1:42.5
We now multiply this ratio by 28 to find out how many are printed in 28 minutes
28:1190
our answer is 1190 copies
