Question

The main printer in the Ivy Tech library can produce an average of 360copies every hour. For every 48 pages, it costs the college $0.3 forelectricity and supplies. If the library is open from 9AM to 9PM, howmuch money does the college use on printing each day?

Answer 1

The college uses $27 on printing each day

Step-by-step explanation:

Given that the library is open form 9AM to 9PM, this is 12 hours

Since the printer in the library can produce an average of 360 copies per hour, it can produce 12 * 360 = 4,320 copies in 12 hours.

Again, every 48 pages costs $0.3

4,320 = 48 * 90

So, 4,320 pages costs 90 * $0.3

= $27
