The main printer in the Ivy Tech library can produce an average of 211 copies every hour. For every 25 pages, it costs the college $0.47 for electricity and supplies. If the library is open from 9AM to 9PM, how much money does the college use on printing each day?

~48$

Step-by-step explanation:

0.47/25=0.0188

0.0188×211=3.9

12 cause of 9am to pm

12×3.9=47$

A (4-7)/(5-3)=-3/2=-1.5

B (7-4)/(3-5)=3/-2=-1.5

C (d-b)/(c-a)

D (b-d)/(a-c)

Step-by-step explanation:

Identifying (x₁,y₁) and (x₂,y₂). We will use the formula to calculate the slope of the line passing through the points

slope =(y₂-y₁)/(x₂-x₁)
