C(12/15) because the other 3 all equal 0.666666666666667 but 12/15 equals 0.8
Answer:
3 minutes
Step-by-step explanation:
To calculate this, you have to multiply 4.5 minutes by 8. This will give you the amount of pages that Wafa will print.
4.5 x 8 = 36 pages
Now that you have the amount of pages, you should divide it by the speed of the Sure-Fire printer. 12 ppm means that 12 pages can be printed in 1 minute.
36/12 = 3
Therefore, it would take 3 minutes if Wafa were to use her brother's Sure-Fire printer.
